I've been scheduling some quarterly reports, and would like them to be sent only at the end of each quarter (i.e. April 1st is the day after Q1, July 1st, is the day after Q2, etc).  However, when you check off only a select few months to receive a scheduled report, the "Every Month" check box gets checked; therefore, quarterly reports are send every month, instead of every 3 months.  See photo below:
