I am reviving this old conversation go ask a question. Can you trigger a custom behavior for a SPECIFIC symbol. I have a bunch of toggle buttons that are all one symbol with many instances. I am able track the state of each one by the ID. But it would be nice to be able to call a custom behavior to set each one to a specific value. But it seems that custom behavior hits every instance of the symbol. So I can turn them all off or all on, but I cannot target one to trigger the behavior. Let me know if I am wrong. For now I am just going to write javascript to manipulate the timelines manually, but it is more cumbersome than just being able to use the behavior.
