How to teleport every player to a different location?

I’m working on a Minecraft map. My plan is to teleport everybody (at the "event") to a different location.

So the problem is that I cannot do:

/minecraft:tp @a[team=event] ~ ~ ~

because it would teleport everybody to the same location.

So is there a way to teleport for example using:

event.member1 to 10 10 10

but also teleport event.member2 to 20, 20, 20?
