This is not the same as this request which is also cool.
I would like a field library for teams so I can set up custom fields just within a team.
Use Case
How many variants of Task Progress will pile up as different people set selections based on their needs. If allowed to save to a Team, then the name can be the same, but just at a team level. You can do this on a project level, but then you can’t have progress bubble up into other project within that same team.
