Symantec System Recovery, every other week?

I'm running Symantec System Recovery 2013 and I just have a quick question for anyone out there that might know more about it than myself: Is there any way to set up the schedule to do a full backup every other weekend?

I see there is the monthly options, but that gives me a choice of what days of the month, not what days of the week. Any help or insight is appreciated!
