I just want to be sure I understand what you’re trying to do. Could be I’m just dense today but your question has me confused.
When you create a new post that has the repeater field do you have an add row button and when it’s clicked there are sub fields to enter information into? or do you mean that there are no sub field when clicking the add row button?
I’m trying to figure out by your comments if you’re trying to create the sub fields or trying to add default content to fields that are already there.
