Schedule your Digital Signage content by day

Hi,

Is there an easier way to schedule digital content by day if I need to alternate it by week for a long period of time?

For example, my company deploys e-signage on our TVs and we have bi-weekly reminders to submit timecards for employees/managers. 

Right now I only see a way to add content list from one start date to another, but not the ability to schedule only specific dates. Would I just have to keep adding content list for every other week?
