What do you have for source documents? In my case, I'm using the MS Word files that were produced for for our print material. PDFs were originally intended as a means to present documents in a universally readable format, regardless of source. Editing PDFs is really meant to be more of a quick touch-up process for when you don't want to have to go to the original to make minor corrections. It's probably better if you use your original source material to make the PDF instead of the Rise course.
You could always print and choose "Save as PDF" but you'd have splits in images and text blocks just like regular print, and it'd be a nightmare to fix them.
