Can I use planning function to copy something like this...

Can I use Planning Function type 'Copy'  to copy something like this...

1. hierarchy planning item B copy to planning item X

2. (hierarchy planning item A EXCLUDE hierarchy planning item B)  copy to planning item Y
by the way, hierarchy planning item B is under the hierarchy planning item A.

I want to use parameter 1 and 2 in the same planning function.
Can I implement it?
