Be able to export INDIVIDUAL artboards INDIVIDUALLY as pdfs like you can in InDesign.

When I save as a pdf out of Illustrator it ONLY saves a combined multipage PDF, which the printers that I work with cannot use.  I need to be able to save them as individual pages, like you can out of InDesign.

I attempted to use the Export for Screens function, chose all artboards, and selected PDF. 

This proceeded to create files accurately named after the individual artboards. However the contents of each file was all of the artboards from the original file.
