switching, instead of adding courses error

Hello Guys,

thank you for a great addon. I plan to use it with dripping content as a course manager and testing was ok, it dripped, it was givin the access according to client’s access to the course articles category, but now i found maybe some error.
The situation is that I plan to have maybe 20 – 30 courses on site and the plugin is ideal to add a course to client and drip content to him/her for next few months (f.e. category knitting_course, articles knit1 – knit12, dripped weekly). But when during that course client will decide to take another course (sewing_course, articles sew1 – sew12, dripped daily), client will lost his his first, knitting course access rights. I could of course tell him – one course at a time, but I fear that’s not a good approach. I saw the plugin allowing access to single article, but its not solving my problem – as its about 12 articles / category…

But maybe I just don’t see some option which does it, that’s why I am asking.

Thanks, Peter
