TMENU in Typo3 - insert url from level above - menu

Question

I have a TMENU, and in that menu I would like to insert an URL from "Level 1" into a wrap item in "Level 2".
Current TypoScript looks like this:
10 = HMENU
10 {
1 = TMENU
1 {
expAll = 1
NO = 1
NO.allWrap = <li>|</li>
NO.allWrap.insertData = 1
NO.ATagTitle.field = abstract // description // title
}
2 = TMENU
2 {
expAll = 1
stdWrap.wrap = <ul><li></li>|</ul>
NO = 1
NO.allWrap = <li>|</li>
NO.allWrap.insertData = 1
NO.ATagTitle.field = abstract // description // title
}
}
Any hints? Thanks for helping!

stdWrap properties are executed in a defined order (as they appear in documentation), see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Functions/Stdwrap.html#prepend
Knowing that prepend is executed before wrap3 allows to solve this challenge.
page = PAGE
page.10 = HMENU
page.10 {
1 = TMENU
1 {
expAll = 1
NO = 1
NO.allWrap = <li>|</li>
NO.allWrap.insertData = 1
NO.ATagTitle.field = abstract // description // title
}
2 = TMENU
2 {
expAll = 1
stdWrap.prepend = TEXT
stdWrap.prepend {
# remove `value` if page title shall be used
value = URL from Level 1
# using <current-page>.pid value pointing to previous level
typolink.parameter.field = pid
wrap = <li>|</li>
}
# `wrap3` is executed after `prepend`
stdWrap.wrap3 = <ul>|</ul>
NO = 1
NO.allWrap = <li>|</li>
NO.allWrap.insertData = 1
NO.ATagTitle.field = abstract // description // title
}
}
On a page-tree like this
+- A
| +- AA
| +- AB
|
+- B
+- BA
+- BB
The rendered HTML result looks like this
<li>A</li>
<ul>
<li>URL from Level 1</li>
<li>AA</li>
<li>AB</li>
</ul>
<li>B</li>
<ul>
<li>URL from Level 1</li>
<li>BA</li>
<li>BB</li>
</ul>
Update on custom rendering replacing static value property
Instead of using property stdWrap.prepend.value (like shown in example above), other cObject instructions could be used as well - in this case for instance RECORDS (see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/ContentObjects/Records/Index.html)
The following example renders fields nav_title (and if that's not defined title as fallback) of the parent page.
page.10 {
# ...
2 {
# ...
stdWrap.prepend {
# using `cObject` instead of `value`
cObject = RECORDS
cObject {
tables = pages
source.field = pid
# rendering definition for retrieved record of table pages
conf.pages = TEXT
# `//` is used as fallback delimiter here, NOT as comment
conf.pages.field = nav_title // title
}
# ...
