The way to use emojis ONLY on the same server, like NOT-Nitro-users

There are too many emojis with the same name on each servers. ex.)":abcd~9:" I often think "which server? I want to use :abcd: of THIS server." Especially in the case of iOS, I cannot distinguish the names in advance. It is useful that I can switch emojis on other servers to hidden or not, like NOT-Nitro users.
