enable/disable call function

Hi,
what a great programm.
I would like to propose a feature which would be a helpful addition to Discord.

By now I have different kind of people in my contact list. Some are friends i study with, some are people i play games with. So with some people I call a lot but with others I don t want to call with.
How about the possibility to individually disable the call option and maybe also disable the video call option but enable the voice call? That would be a good way to avoid accidently calling random and maybe unknown people without blocking them.

Kind regards
