Need to manage multiple subscriptions and…

Looks like it might work for my needs, but I need to verify before purchasing:

Basic flow: I’ll have a video site, containing vids on topics a, b, c, d. Users will then subscript to any/all of those topics, at $10/mo (via Paypal). per topic.

– Someone sign up for content a, b, c, d (each @$10/month)
– WP content shown based on the a, b, c, d content area they have signed up for
– they can change IN or OUT of the a , b, c, d categories, which will adjust the subscription they are part of.

Will the Pro version allow me to do this?

Thanks
