How can I save a group of submissions as pdf?

I need to save a few submissions as a PDF.  If there a way to select 20 submissions for pdf instead of all of the submissions.

You can download the submissions from the submission viewer by following this guide:

Go to the form submissions viewer.

Click on the submission you want to delete as PDF. And click on the PDF button. 

You will have to do this for every submission you want to download.

Let us know if you need more information.
