Single Download of PDF files with Multiple Check Boxes

Discussion:
Multiple PDF file download to one file

I have a product builder application where the user can select one check box from Various options, then select another check box and then a 3rd. Ideally want to then have a “Single Download Selected Files” the user can click and a single PDF file will take the 3 options from the check boxes and merge to one file that is automatically downloaded. Is this possible?
