Change Visibility Tool - Single UNDO action

When using the very useful Change visibility Tool, what currently happens is that the user can select some elements and change the colour, transparency etc. Most of the time, an exercise like this will likely be done in a few stages. If teh user makes mistake during this process, there is no option to UNDO the last selection and change. you have to click on the 'SHOW ALL' button to restart, loosing all your work. a Option to do a single step UNDO, would be very useful and save a lot of time if teh user made a mistake
