SharePoint List UserCustomAction, In whole sitecollection - sharepoint

Question

I'm getting this to work if I choose a specific list to add the action to. Is there an easy way to enable this custom action on all document libraries in the whole sitecollection?
Code sample:
function createUserCustomActionList() {
var cmd = "<CommandUIExtension><CommandUIDefinitions><CommandUIDefinition Location=\"Ribbon.Documents.Manage.Controls._children\">" +
"<Button Id=\"DiaryAction.Button\" TemplateAlias=\"o1\" Command=\"DiaryCommand\" CommandType=\"General\" LabelText=\"Dela flera\" Image32by32=\"https://eolusvind.sharepoint.com/sites/intranet/_layouts/15/1033/Images/formatmap32x32.png?rev=23\"" +
" Image32by32Top=\"-271\" Image32by32Left=\"-109\" />" +
"</CommandUIDefinition></CommandUIDefinitions><CommandUIHandlers>" +
"<CommandUIHandler Command =\"DiaryCommand\" CommandAction=\"javascript:alert('Hej');\" EnabledScript=\"javascript:SP.ListOperation.Selection.getSelectedItems().length > 1;\" />" +
"</CommandUIHandlers></CommandUIExtension>";
var ctx = new SP.ClientContext.get_current();
var list = ctx.get_web().get_lists().getByTitle('Dokument');
var uca = list.get_userCustomActions();
var oUserCustomAction = uca.add();
oUserCustomAction.set_location('CommandUI.Ribbon.ListView');
oUserCustomAction.set_commandUIExtension(cmd);
oUserCustomAction.set_sequence(100);
oUserCustomAction.set_title('Dela flera');
oUserCustomAction.update();
ctx.load(list, 'Title' ,'UserCustomActions');
ctx.executeQueryAsync(function () {
alert('Custom action created for ' + list.get_title())
}, function (sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
});
}

I would suggest the following approach for registering custom button in Documents libraries across site collection:
use RegistrationType set to 2(ContentType) and RegistrationId set to 0x0101 (for Document content type) to register custom action via content type
use site scope user custom action to apply changes across all site
collection
Example
var cmd = "<CommandUIExtension>" +
"<CommandUIDefinitions>" +
"<CommandUIDefinition Location=\"Ribbon.Documents.Manage.Controls._children\">" +
"<Button Id=\"ClickAction.Button\" TemplateAlias=\"o1\" Command=\"ViewCustomPropertiesCommand\" CommandType=\"General\" LabelText=\"View Custom Properties\" Image32by32=\"/_layouts/15/1033/Images/formatmap32x32.png?rev=23\" Image32by32Top=\"-1\" Image32by32Left=\"-171\" />" +
"</CommandUIDefinition></CommandUIDefinitions><CommandUIHandlers>" +
"<CommandUIHandler Command =\"ViewCustomPropertiesCommand\" CommandAction=\"javascript:console.log('View Custom Properties');\" EnabledScript=\"javascript:SP.ListOperation.Selection.getSelectedItems().length > 0;\" />" +
"</CommandUIHandlers>" +
"</CommandUIExtension>";
var ctx = new SP.ClientContext.get_current();
var customAction = ctx.get_site().get_userCustomActions().add(); //1. apply via site scope user custom action
customAction.set_location('CommandUI.Ribbon.ListView');
customAction.set_commandUIExtension(cmd);
customAction.set_sequence(112);
customAction.set_registrationType(2); //2.set to ContentType
customAction.set_registrationId("0x0101"); //2.set Document content type
//customAction.set_title('Document custom button');
customAction.update();
ctx.executeQueryAsync(function () {
console.log('Button has been registered');
}, function (sender, args) {
console.log('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
});
