Nitro Boost Reward, Server Chat Catagory Backgrounds

It would be nice if each Category could be assigned a background to display in its chat room. It could work as part of the Nitro Boosts. It would allow people to give themes to each category to help people better differentiate them. My server has multiple categories for general, games, campaigns and planning/work. Everything looks so similar it would be nice for a change.

Either by going through nitro boosts, or if they plan to have a paid upgrade in general for servers.
