Preference offline

This game has been out for years and the feature to put preferences offline is still not a thing. Sometimes I just want to get on and play solo without getting spammed by friends to invite them. I understand the "don't add them if you don't want to play with them", but I do enjoy playing with friends. Just sometimes I just want to play solo and relax. Xbox did this feature and it was great, plenty of people ask for this feature and it wouldn't be that hard to do honestly. It's just a simple button like the "busy" player status. Maybe just add a third click to make your preferences offline? Would be a great feature and I'm sure a bunch of players would appreciate it!
