Every weekday repeats, and the like, aren't natively supported yet. There are two work-arounds. You can use the Defer script (available on the Extras forum) to push the Saturday instance of your Daily project back to Monday. Alternatively, you can create five copies of your Daily project, one for each weekday, and set each to repeat on a weekly basis. Most people seem to use the latter option, though if you decide to change your routine, you have to change all five copies.
