How to divide FG bodyslides

[Lone_Wanderer_IT]

I wanted to begin on adding FG bodyslides for some CBBE outfits, and after many attempts I finally managed to create some.

But I don't know how to "divide" the FG bodyslides from the CBBE ones, as when I save them I just changed the display name to recognize them from the CBBE versions.

So, how can I safely move all the FG slides without riskying to redo the slides from the beginning?
