Permissions audit: see group membership

I'm a project admin but not a Stash admin. We have been encouraged to use groups rather than users for permissions... but I can't see group membership, and I need to be able to verify who's in a group.

Is there any way you can add the ability to see group membership to project admins? I don't need to add/remove users to groups, but I do need to verify who's in the group.
