Pick Days of Week for Weekly Task Emails

I would like to be able to choose which days to process email tasks weekly. For example, if I would like to remind someone to do something Monday, Wednesday, Friday each week (if still applicable). I have to create the same exact email 3 times and make it repeat weekly on each day. Even worse, if I want to email during weekdays and skip the weekends... now I get to create the same thing 5 times. :) Much simpler if I could choose weekly and be given a checkbox list of Monday - Sunday and just select the days to fire the task on at the given time.
