This is still unclear. Imagine you have a pattern and kit saved. As you tweak the notes and sounds, you come up with a worthy new scene.

save the new pattern
get back to the old one

and here… unfortunately, the old one is linked with the new kit, and to get back to the assignment of the old kit you need to reload it here.
