Comment 4 for bug 1837002

Another way I can see of getting the functionality is to add a context menu entry to blocks that says 'move block to sheet' which brings up a pop-up selection of which sheet to move it to. Don't know if that might be easier or somehow preferable to 'Paste Special'. It would remove the issue of duplicate references though that could be fixed with 'Paste Special' by graying it out once you've pasted once or if the original move was a copy rather than a cut.
