make the polyextrude take only the last extrudedfront group (not all prior ones)

[anicg]

Attached hip file. I'm using 4 polyextrudes everytime with extrudefront group, the problem is that it uses earlier ones as well, even when I uncheck preserve groups, I only want the last extrudedfront, not the one from before that last node. I can use different names but it will be cumbersome dragging a lot of groups down the network. How do I make the polyextrude take only the last extrudedfront group?

@anicg There is no way around doing this except renaming the extruded group name.
What you could do if you plan on doing this 50 times in a row is write an expression that does the numbering for you.
Here is how you could approach this.
