Display Roles Separately, but in specific channels

We can display roles separately overall, but not in each channel.

Basically, if I wanted the role @/Gamer to show up separately from the rest of the users in the specific channel #gamers, then it only shows up in that channel and not all channels. 

An option in each channel for each role to choose whether a role will display separately or not would be grand!
