Multiple Actions on a Button

I think this would be useful if a button could also specify a "group" that bookmarks can be placed in. The results could then reflect the aggregation of the bookmarks in the group applied in order the bookmarks are shown in the group. E.g. When showing visuals with bookmarks, one bookmark could be made to show just one visual with a specific button, but another "Show all" button, could show all the visuals relating to all he bookmarks in a group. You can then simply add in another bookmarks to this group without having to add them to the "Show All" button properties For ease of I would also like the visuals to be able to be synchronised across bookmark groups too similar to slicers across pages of a report. I could then specify the change to one visual (e.g. slicer value or visual visibility) and opt for it to be set the same for the bookmarks or Bookmark groups I tick. This would be especially useful for adding or changing visuals to lots of pages in the report that have their own bookmarks already set up. Currently, when I have a slicer synchronised I have to bear in mind which bookmarks may set this slicer independently and spend time updating those bookmarks.
