I think I’m trying to run before I can walk! 
I created TargetPoint instances named TeleportPoint_x and in each of these I change the variable ID default value:
I can actually extract all the info from each “teleportpoint” using this debug code:
which gives me the correct output of each of the teleportpoints:
What I can’t do, is reference the ID variable I have created in those instances:
I have tried “ID”, “teleportpoint”, and everything I can think of!
I really appreciate your time and help with this - as people have often said, you certainly deserve that hero title! In reality, I could explicitly define a small number of locations and rotations manually for my use case - I am interested in this because it makes more sense using your approach.
