One-per-week download subscription?

Can you please tell me if this is possible with s2Member (either the free framework or the Pro version):
I need to set up a site to sell a subscription that allows a user to choose from among a set of file downloads, but each week have access to download only one of them, from among the available choices.

From the listed features, it says that S2Member can limit how many times a file can be downloaded by a member… but it’s important to be able to limit a member for this from downloading ANY file once they have downloaded one.

The “hack” way to do this would be to set up an online store w/ digital downloads, and send out a weekly coupon code… but that’s too cumbersome for both the user and the site administrator.

Also, there would need to be some way of clearly displaying the status of their downloading availability (either near the download button, or as some kind of umbrella over the whole site, i.e. “download credit available/used”)… that’s not crucial, but would be a big plus.

Thanks

Unfortunately, this isn’t possible with the current features, however you may be able to use the s2Member Hooks to create your own custom hack to make this work.
