Customize server icon for other servers

I have a number of discord servers I've connected to, and a number of them a) change the icon often b) have icons that are generic c) have NSFW icons d) etc. 

I should be able to customize the icon of servers just for my own viewing so I can keep track of servers more easily. 

An example is I belong to a Tottenham Hotspur server, and they love to meme the server icon with the latest memery related to Spurs, but at a glance I can never remember which one is which. I'd love to just change it to be the Spurs icon (for me only, not everyone) so I don't have this problem.

This seems a perfectly reasonable idea, like how in Steam you're allowed to give steam users personal nicknames
