Re-Mapping a tree

Hi all,

Specific tree re-mapping question here, I believe it involves the Path Mapper but I've always struggled with it.

I have 3 sets of referenced points. I want to drop them into one single Pt container, but have them each in their own 'grouped' branches. Putting them together just flattens them, while grafting before putting them together groups one point from each group. The ideal syntax I'd be looking for is:

(0) N = ['n' value for NT_100]

(1) N = ['n' value for JL_200]

(2) N = ['n' value for CB_300]

So that there is Data with 3 branches, one for each set of points. However, Im unclear as to how best to achieve this. Help is always appreciated!
