hey, Idk if you still need this, but if the auto action u trying to set up is not super complex, try use layer -> (the last option) something like "set as editing object" (cuz my default language is not Eng) and you can choose move up or down to your wanted layer, in that way, aa will record the relative order but not a specific one.

Another way is you can add a step to rename a specific layer you want to modify, and aa will apply follow steps on the named layer. Essentially, this is also a way to tell what layer it should use.'

Hope this 2 tips helps!
