Ok, I can change the form. But we need to have some functionality for the new field. Namely, we'd like to connect users with corresponding operators depending on selected city. It's very similar like the department field works.

I see only two options here:

1. we can rename department field to 'city' and use the current functionality in order to divide operators by city.

2. if we need both department field and city field we need the full source code license in order to rewrite the script under our needs though this case is more complicated and costly.

are there another solutions?
