There should be a button which you can toggle "allow", "deny", or "requires permission" when copying base instantly because MFs that usually goes in hopper mode is annoying, you can't even block them out because of clan leader keep inviting hoppers then copy your base then leave. There should be some kind of button in settings or profile (well it can be in settings).

I know it was hard to create a new function for that so that's fine if my idea gets buried or I hope there is someone who already done this post.
