FSM Create an unavailability pattern

Hi,

Is it possible to create an unavailability pattern in FSM or PSO?

We tried to look at calendar exception from the Person menu and in the PSO directly, but you can only create unavailabilities in a time interval. What we want is, for one unavailability, to create more of that same unavailability with the same duration and for each day of the week.
For example, create an unavailability that always repeats from 9am to 12pm from Monday to Friday.

Does anyone know if this is possible?

Best regards
