Group Rows - Parents & Children

Hi everyone,

I’m hoping to get some help from the community. Is there a way to automatically group rows in a parent-child format?

For example:

1. Parent A
   • Child A
   • Child A
2. Parent B
   • Child B
   • Child B
3. Parent C
   • Child C
   • Child C

Each time I add a new row, I’d like it to automatically group based on this logic.

If I add a row name "Child C" I want it to group to the Parent C and so on…

Thanks in advance!
