Gh pattern with more than one surface

I’m trying to make a pattern with surfaces. I can’t do it if my starting module presents more than one srf.
I attach here an example with two numbers but I would like to do it with a group of surfaces.
Is there anyone that can help me please? Thank you in advance.

You could use Group from the first place.

Hello @valeria2 you can use the Group component to make the list hirerchy simpler. Is this sonething that you are looking for?
