iControl SOAP: Get list of virtual servers using an IP

Does anyone know which method in iControl soap I should be using to retrieve a list of virtual servers utilizing a specific IP address? get_list() returns a full list and doesn't seem to take any arguments while get_address() also returns a full list.

I'm trying to write a script in Perl that will check to see if a given IP address has pre-existing virtual server configurations--almost like a reverse lookup but I can't seem to find any method under LocalLB/VirtualServerV2 or LocalLB/VirtualAddress that will allow me to find a specific set of Virtual Servers based on IP address.
