Multipage PDF export in the Asset Export Panel
The Asset Export panel is really great and you can export Artboards as PDF but each artboard is a PDF file.
It will be so great to add a checkbox to export the selected Artboards as a unique Multipage PDF.
Currently you can export in PDF using Save as… PDF, you have to enter manually the pages ranges and it's not memorized for the next export like in Export for Screens (Asset Export panel).

A friend (thanks Cary) is remembering me that an option Full Document is available, but with this option it's the entire document that is exported and not a selected range of artboards exported as a unique Multiple Pages PDF.
