Does Provider Working Hours in A+ really only allow weekly recurring hours??

How can we allow a service provider to set their availability hours different for each week? As it looks now, there's only a weekly recurring schedule. I'm obviously missing something. I dont know anybody that works the same hours every day of week...every week.

We need to be able to set the providers days/times for this week separate from next week.

For example, "Bob" works Tues - Sat this week, Mon, Tues, and Friday next week, and Wed - Sun the following week.
