Yea, I'm sort of figuring that out, I was hoping I could find some way where it "knew" it was created in the existing phase by some built in parameter, and tag accordingly.
(versus simply selecting the proper tag to label them with)
you can do this but not in way you want to... use views instead..
have two views, one view showing existing phase, the other showing new phase.. use tag all on both views, using proper tag. copy/paste into your sheet and all is good..
