CBSubs give access one week or month at a time?

I want to do a monthly subscription for lesson plans. These lesson plans would be a series that would last for a year. I would not want them to have access to the full year of lessons plans at once. I would want them to be emailed weekly with links to their lesson plans for the new week and only have access to those and all the ones they've had in the past, but not anything more.
They would start with the first week of lesson plans whenever they signed up.
Will CB Subs do this?

You would have to use CBSubs and CB COntent plugin (available to professional members) to do this.

The concept is to surround each Joomla content article with bot statements that should content only during 1 month of subscription, 2nd month, etc.

This is the only solution I can think of at the moment for time released content (thats the term i believe).
