I would like the “unflatten” tool to have the option to only unflatten the current page and or even just a selected area.
I use BBR to do take off and as I enter in to estimating software I flatten the markup.
It is possible to only unflatten certain pages in the "Flatten Markups" dialog, you can choose the page range in the top section before clicking "Unflatten" at the bottom.
Nice find @A1ex Smith! I hadn't noticed that you could select the page range on this menu.
