Copy & paste takeoff items using the pages panel

Just realized that you cannot use the pages panel (left side panel) to copy & paste a page's takeoff items to another floor.

I thought on the left panel options menu that I saw 'Copy All Selected Items' right here above the 'Delete All Selected Items' a week ago but I guess not

Presently the only way to copy all items from a page is by dragging a mouse selection box over all takeoff items (or holding shift and clicking each one individually).

Using the pages panel would be much faster, plus it would make it easier to only select certain takeoff items rather than needing to draw selection boxes over them.
