Displaying and Numbering Text from Repeating Group List

Need help App Organization
1

Hi, I am trying to populate a Multiline Input with a list of text items from a Repeating Group / RG. I currently have:

"Object’s Text Attribute: Join With “Line_Break” which successfully populates my Multiline Input’s placeholder text to:

Text1
Text2
Text3
…

I am wondering if there is some simple way to have each line of text be numbered? One hitch is that the number of Text lines to be displayed will vary (I am also filtering the Text’s to be displayed but omitted that from above for simplicity).

Additionally, it doesn’t appear as if I can use the “Join With” operator a second time.

Thanks a lot!
