Promotion based on length of paid membership?

[troux]

I have a site that offers a premium member level for a yearly fee. I just started this feature about a year ago, and a bunch of accounts are going to be up for renewal.

I want to both reward and encourage members who subscribe for a 2nd straight year. Based on my understanding of the built-in promotion system there is no way to do this. I basically want them to be promoted to an additional "2year" group if their paid subscription time has been more than 365 days.

I apologize if this has been addressed before or if this ability already exists-- I searched quite a bit but didn't find any related results.

Thanks!
