Allow default splits by group.

Im a PM so tacking my chance in sharing a user story you can try to implement direct if you agree 😝

User story:

as a user that as a family budget in which different people pay different %

I want to be able to set default of share of expenses to each group member

So that I avoid editing manually each expense

acceptance criteria:

1. on group settings add a default split area

2. List each member and have by default 1/<number of members> populated

3. Allow the user to edit the % for each member

3. Apply by default the saved percentages ok new expenses (new setting)

4. Fix the experience on the current manual edition of % o by editing automatically the remaining group members if one is edited (e.g., today if I select 60% for one member in the group of 2, the other member keeps 50% - it should auto change to 40%). If the group has more than 2 members edit always automatically the non manually edited people by dividing the rest of the percentage by those not edited. Have this behaviour both for the manual editing of an expense and for the default split (new feature described here).
