@tzzz - I can sympathize - we hit the same issue where adding a new Vendor is reserved for Account Admins only - it seems a bit of overkill and a likely bottleneck as well.  Perhaps you can submit this as an Idea.

@tzzz have you submitted a ticket? If there isn’t a solution, it can be requested to be added as a future enhancement release!

Has someone found a way to make this work with the over power option?

This would be a great feature for us to have so our Finance team could assist with contract management.
