It would be helpful if Import Markups had the option to also import the Header & Footer from another PDF.
My workflow is to print updated calculation packages to PDF and import the markups from the previous version. The header and footer stay the same every time, but I have to recreate them after each import.
In addition, if there were options to choose what to specifically import, such as Markups, Layers, Header & Footer, Bookmarks, or Page Labels, instead of only importing markups.
