Is there a possible filter, or something anyone knows of to do the following:

I'm attempting to run a game server, with a specific game that players can find team mates for.

However when someone is on another game I'd like it if the server ONLY shows players who are displaying that they're on this specific game.

Is that a possibility? Example:

Let's say I host a minecraft server, and I have a player in my server who is playing Rocket League, is there a way that I could hide anyone not showing Minecraft so that way players can attempt to find groups easier instead of pinging everyone, or just hoping for a response?
