How can I create two regular courses that have the same schedule but every other week?

It will be necessary to create 2 separate courses with fortnightly frequency and start them on the same day but a week apart. (e.g. Monday, 15/01 guitar course, Monday, 22/01 piano course, and so on).

By doing so, the two courses characterized by the exact same schedule but staggered by one week, will alternate precisely without creating calendar conflicts.
