Manager front end: filter values in Person's department field

Hi,

Working in 8.1.3, and just as it is done in the web portal, is there a way we could filter out the list of departments (Person.UID_Department) that can be selected in a person's Organizational form in the Manager front end?

In general terms, in the Manager front end, how could we modify the list of fields available for an object, as long as their contents (ie, the list of departments that can be selected for a person)? That's easily accomplished in the web portal, but I could not find any reference at all for the Manager front end in the documentation.

Thanks!
