EXPERTS! How to teleport specific players out of many others?

Guys, I’ve made 3 maps and all my work to let 3 (for example) players teleport out of some place among many other players is to make a volume and let it move using cinematic device, once these 3 players enter this volume it sends a signal to the teleport device to teleport these 3 players.

It’s exhausting, I believe there is a more professional way to do that. Experts, enlighten me :smiley:
