Primitive node "control_after_generate" loop?

[VikingTechLLC]

I think there's ways around it, but requires a lot of other nodes to make it "work".

Would it be possible if Primitive Node had the ability to loop through the connected list if on Increment (or decrement)?
Two situations:
Connected Primitive to a Boolean_number, available options are 0, 1. On increment when you generate an image from 0, it moves to 1, but then just stays there indefinitely. If it had to ability to loop you could go 0,1,0,1,0,1,0,1,0,1,etc at each image generated.
Likewise if connected to say a list of checkpoints, it will increment through your list, but stop at the end indefinitely.

If it's entirely not possible, that's fine, but if it would be a relatively simple change to add a loop feature for it, that would be amazing.
Thanks
