CoursePress Pro Feature Request: Configure tcpdf inside of certificates

It would be nice to be able to configure various settings for the tcpdf portion of Coursepress pro without having to edit the tcpdf_config.pdf file in code. What I mean is being able to change things like page size, default fonts, margins, etc. from within CoursePress settings. In my instance I actually just needed to change from A4 paper size to LETTER. This is a very simple change in the config file, but it is another thing that I will need to ensure that I change on every update.

Would it be possible to read those settings from the wordpress database instead of the config file? Maybe store them in the database from CoursePress and then use custom mySQL in the tcpdf_config file to call the settings from the wordpress database and set them to the appropriate definitions?
