Different schedules on even or uneven weeks

We have a number of colleagues who have a contract for 36 hours a week, but work 40 hours a week in the even week and 32 hours a week in the uneven week. We also have this for 28 hours a week (24 hours in an uneven week, 32 hours in an even week). Now I have to manually set a new schedule every week and that really doesn't work well. Is there a solution? With another software that we use, we can check the box with 'even and uneven weeks deviate' and thus set the distinction. How do other companies do this?
