Assign values to downloads

I know s2member doesn’t currently support a token/credit system for downloads similar to a lot of stock image sites that deal with downloads for various image resolutions, each with a different credit value.

What I’m wondering is if it’s possible to assign a value to downloads from a certain directory only (even if I have to hack the code), to count as 2 downloads instead of just one, creating a pseudo credit system.

For example: everything in the “medium” sub-directory inside s2member-files would count as one download (unchanged), but everything in the “large” sub-directory would count as 2 downloads each.

I looked in to custom capabilities since you can only assign one member level to each user, but I can’t seem to find a way to accomplish this.

Other than this particular functionality, s2member seems perfect for me.
