Work Profile with Weekly hour target instead of daily

We would like the option to set up a Work Profile that only triggers a conflict if the total scheduled hours for the week exceed the target.  Right now a person could have a 10 hour per day target M-Sat (i.e., 60 total hours) and only be scheduled for 50 total hours but if any one day exceeds 10 hours a conflict appears.  We don't care which days the staff do the work we just want to make sure they aren't scheduled for more than 60 hours in the week.
