Would a Pin to UID action be possible?

Does anyone know if something like this would work for the Pin behavior?

We're looking for a way to automatically pin an instance to an UID when the instance is created in layout without requiring events by using a behavior property, a sort of equivalent of the child/parent tree system from C3, we thought it would be useful for menus and interfaces

Thanks in advance

Without any event that would be impossible. Anyway here chaining pin examples based on IID:

I already know how to pin by using events, IID, loops, etc; my question was specifically about selecting an UID directly in the behavior script, but if that's not possible, then nevermind
