Be able to block one emoji if they have the same name

Sometimes you have two emojis with the same name (sometimes with a difference in capitalization), which can get very annoying when you are in a server for certain emojis but not other ones. So, you should have the ability to set one as a default, or block the other one(s). This would make it so that you can comfortably use the emoji that you want instead of the other one that keeps being defaulted to for some reason.
