How to undo a slice without losing subsequent edits?

CloudMonkey Posts: 11 Just Starting Out*

I'm still new at this so sorry if it's really simple. If I make a series of slices, for example in order 1, 2, 3, 4. Then I add effects and transformation to each snippet. Suppose I now want to go back to slice 1 and undo just that slice and the edits I made to those two snippets, but without losing all the edits to slice 3 and 4. Is there an easy function to undo slice 1? Thanks
