Schedule email for multiple dates without making copies

From a dynamic email list that I have constructed in DonorPerfect i would like to send the same email at the first of every calendar quarter.  Because this email list changes every quarter based on a DP filter (member expiration date in the next calendar quarter) the scheduled quarterly email would not go to the same constituents. We are looking to remind members that have an expiration date in the following quarter to renew their membership.  

Currently I have to copy/save last quarter's email and then schedule it for the future date.  This is a repetitive manual process that new functionality would make much easier and streamlined.  We have the technology; can we use it?  Thanks for the consideration.   -craig dickstein, Maine Appalachian Trail Club
