[HOW TO?] use arguments as pointers in subpatchers/abstractions

Hello everyone

I have an hierarchy of a main abstraction which has inside, in a sub-level, two small abstractions that are quite similar but differ in some points and I want that the argument in the main abstraction, namely a #1, is mapped to another #1 in those two abstraction that are encapsulated in the main abstraction . is that possible to do? If yes, tell me how..

thanks in advance
