An option to have group chats blocked/toggled

I think it'd be a good idea in somewhere like the privacy settings to have a few options regarding group chats, the fact of being added to them, then leaving, then being added again even if I remove and block the people is starting to get tedious and annoying especially when it happens daily.
Maybe options like:
I don't mind group dms (default/normal)
I prefer to be asked to be added (gives you a pop up saying [BLANK] wants to add you to a group do you accept/decline)
I do not like group dms (completely declines group dms)
Just a concept idea! it'd be nice to have the option to decline/toggle group dms.
