access by reg date for recurring subscription

I need to address the 2 following conditions and need to know if your plugin can do this:

1) Access based on paid registration date for recurring monthly subscriptions. New content will be posted each month. A user who begins membership anytime during the month will have access to the entire months paid content, and then with recurring payments will have access to each month going forward, but not for months previous to their registration date. So if Joe buys a membership anytime in January, he will have access to January forward as long as his membership is paid each month. However, if Sally buys a membership in May, she will have access only to May forward and not January thru April – for example.

2) There will be an option for new members to purchase access to the months previous to their registration date on a per month basis, so Sally in the above example could purchase any of the previous months by paying a one-time fee for that month as long as she is a current member.

s2Member currently doesn’t handle situations like this by default. I believe the only way you could accomplish this would be to sell Custom Capabilities for each month’s post(s). Then either have Users sign up for each month (or buy a new Custom Capability for each month), or have a process using s2Member’s API Notifications to automatically give subscribers access to new Custom Capabilities as you create them.
