No, currently the ExportPDF service does not have a batch functionality. It's a good idea - thanks for the suggestion. Why don't you create an "Idea" on this forum so others can vote on it.
Acrobat does have this batch capability.
Good day Johnny_xlib,
ExportPDF does not have a batch convert option. It's a great suggestion though, and I'll pass it along to our product team.
Update - As you can see from Dave's response, the product team is already aware!
