More Granular Permissions for Moving Messages

Hi!

I'd like to be able to restrict moving messages between workspaces.

For example, I have an IT workspace that I'd rather users in my Production workspace not be able to move things to. There may also be inboxes in a workspace that people shouldn't be able to move things to (I'm open to either NO ONE can move things to it, or only people with access can...), like an Executive or Management inbox.

Thanks!
