UNDO button in scheduling

In the scheduling page, I would love an updo button!

I often select multiple shifts to do a bulk change using the "take action" options - a feature I love EXCEPT when I forget to uncheck my items and then do a 2nd bulk change.

What happens: I select shifts, do a bulk change then the list updates based on my revision. It reorganizes itself and sometimes your shifts no longer show on screen if your have a certain filter applied or have changed the date or similar.

YOU MUST look at how many shifts are selected before applying any further bulk changes. Otherwise, you may end up revising shifts that you did not intend to change.

THIS IS ANNOYING.

I can see the advantages of keeping shifts selected if you need to do another change to the same shifts AND if they all remain visible on your screen.
