SDP - Departments - Default settings

I've got only 48 departments, and they are free (don't have any connection\relationship)

If I chose  Helpdesk - Departments for  - Dep 1

It will show Dep 1 with all connections\relationships

So, the problem is, after sync with AD, I've got 61 Sites and only 48 departments (in default settings)

that's why I can't make a business rule that will apply in all sites or departments that in the system, because in BR we've got only - department option that works only and shows departments in default settings.

How can I create a business rule that will apply for all sites (need to choose some sites in rule), or how can I create a copy of all departments when AD sync.
