In TP6.19 is it possible to create inplace subsets with same names?
I'm trying to create similar groups for top level numbering but contents of each group being different.
over simplified example:
Item (to be numbered)
Part-A
Part-B
Item (to be numbered)
Part-C
Part-D
Item (to be numbered)
Part-E

two part follow up questions.
1. is there any documentation on the subsets? in the what's new or another white paper?

2. under the inplace subset feature, what's a serial set?
