Can Arrowhead add a way to appear offline

I'm trying to avoid someone in particular and not let them know I'm online but in helldivers it will always tell them I'm online. And I don't wanna block the guy because he's still somewhat fun to play with. But I want to avoid them and my only option seems to be to get off when he gets on. So I was just wondering or suggesting if they could add the ability to appear offline. I know it won't happen but I figured I'd suggest it anyway.
