Sticker creators need more resources

I have been creating stickers for awhile now, and storing them is becoming very unorganized. 

Stickers have been a big part of my servers, and have filled a few fully boosted servers and now have over 20 servers with the basic 5 stickers on them. I was using custom stickers of players in game avatars for rewards in a VR Esports League, but have had to stop as the server was full, and not all winners have nitro, ended up having to gift a nitro sub to a few people to be able to use their stickers from one of my back up servers. 

I would very much like to see a discord market place for custom stickers, or some avenue to submit sticker packs for approval to be used on all servers as opposed to only the server they are on if you dont have nitro. 

Alternately double or trippling the amount of server sticker uploads would help in the short term but is not the overall answer.
