Coursepress Pro - course length and pdfs

Hi

i have 2 questions:

1. I am looking for a way to set the length of course for a set period (12 months) following enrollment.
It looks like this was a requested feature 2 years ago so i wondered if it is available yet

2. I am using a plugin to show embedded pdfs in the modules. The first one loads perfectly but on clicking 'next' the pdf does not load in the next page - it loads if you refresh the page but i want it to load automatically
The plugin is PDF Embedder Secure - there's some troubleshooting info in this page for reference https://wp-pdf.com/kb/
I'm wondering if this point is relevant :-
'The viewer doesn't display at all (or at wrong size) when inside a Javascript based tab or ajax page transitions'

would appreciate any advice
thank you
