How can I do a prioritization change in Bubble repeating groups that is local to that group?

I am make a Group.

That group has 10 people.

I want to be able to change the order of that group, the first being the most important.

I can’t set a priority number on the User because another person may make a group with that person and their number would be different, so it would have to be specific to that Group.

The person could also be in a different Group of mine and have a different priority number.

Anyway, how would I go about accomplishing this? (I would like to use arrows to move a user up and down the priorty list)
