Starting to use CDK, having some issues

I’m trying to create a custom mission that allows me to spawn all the tanks in the game so I can test some things with them. I’ve watched some tutorials and similar guides, but the methods they use either don’t work for me or aren’t exactly what I’m looking for.

What I want is a mission with a spawn point where I can bring any vehicle from my lineup (that I own) and spawn them in freely. I tried setting up a sphere as a spawn point using actions and triggers, but it didn’t work. Then I followed another tutorial where the person used an actual tank model as the spawn point. That kind of works, it lets me spawn, but it forces me into that specific vehicle.

Is there any way to make a proper spawn setup that allows the player to bring their own lineup and spawn like in a normal match?
