Sort groups and keep spaces - excel

Question

I'm looking for help on a code where the end user hits a button and it sorts the data, but keeps the "groups" together (from columns A through AA) as well as the spaces between tasks.
I've done some research online, but wasn't able to get anything to work, so I don't even have a base code to start from.
Here's some pictures to show what I'm trying to accomplish.
The first image shows the tasks as they may have been entered, but then we assign priorities after all tasks are entered and, as you can see, they're out of order.
Then I'd like for them to hit that "sort" button on the top left of the image, and it sort the worksheet base upon priority, with 1 being the first task, and going down to the last, but keep the "groups" and the space between tasks, so it ends up looking like this:
Again, columns affected would be from A through AA (i.e., the data needing to stay together spans between those columns).
I don't know if this is even possible, but any help would be GREATLY appreciated.
EDIT:
I created a thread on ExcelForum so I can post an actual spreadsheet... that post is here: https://www.excelforum.com/excel-programming-vba-macros/1362269-sort-groups-and-keep-spaces.html#post5585545

Answer 1

Use 2 spare columns to hold sort order keys.
Option Explicit
Sub sortit()
Dim wb As Workbook, ws As Worksheet
Dim LastRow As Long, r As Long
Dim p As Integer, n As Long
Set wb = ThisWorkbook
Set ws = wb.Sheets(1)
With ws
LastRow = .UsedRange.Rows.Count + .UsedRange.Row - 1
' use column AB,AC for sort order
For r = 4 To LastRow
If .Cells(r, "A") > 0 Then
p = .Cells(r, "A")
n = 0
End If
n = n + 1
.Cells(r, "AB") = p
.Cells(r, "AC") = n
Next
With .Sort
.SortFields.Clear
.SortFields.Add Key:=ws.Range("AB4"), SortOn:=xlSortOnValues, _
Order:=xlAscending, DataOption:=xlSortNormal
.SortFields.Add Key:=ws.Range("AC4"), SortOn:=xlSortOnValues, _
Order:=xlAscending, DataOption:=xlSortNormal
.SetRange ws.Range("A4:AC" & LastRow)
.Header = xlNo
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
' clear columns
.Columns("AB:AC").Clear
End With
MsgBox "Sorted"
End Sub
