Hide visuals through a toggle button / exclude visuals from bookmark

When using a bookmark to hide visuals as a toggle button, you can not use more than one toggle button in the same page to do this with a separate pair of visuals, since there is no way to exclude visuals from being affected in a bookmark.

I don't know how hard it is to implement, but the bottom line is that it'd be cool to have a way to limit the scope of those bookmark-toggling / visual-hiding buttons to a couple of visuals, so the rest of the visuals in the report page are not modified / hidden / whatever.
