Repeating Group Ordering

I’m creating an FAQ with multiple repeating groups stacked on top of each other. Each repeating group holds the Q & A’s of that section. For sorting purposes, I could assign each question a number, but poses a problem in the event I want to revisit this page and want to insert a question midway through a section? It would be inefficient to renumber each question. Are there any suggestions as to how to solve this problem?

I ask because I previously ran into this issue in a different context. There must be another way to think about this…
