Add the ability to specify a specific number of days in a schedule.

Building on : http://support.yodeck.com/forums/301815-general/suggestions/13294017-weekday-filter we would like it to be possible to specify a specific number of days for the "Every" field (recurrence). Many restaurants use a menu that cycles either weekly, biweekly, triweekly, etc. (In most cases here we have a tri-weekly menu rotation). What would be great in the scheduler is to be able to schedule a show “Every Monday” or to repeat “Every 3rd Monday” for example. Microsoft Task Scheduler in Windows is an example of how this would work.
