Network outlet documentation

We have a lot of projects where we need to document witch network outlet the installed equipment is connected to. Because of this we would very much like to have a separate text box for "Network Outlet" added to the equipment properties just like we now have serial number, IP address 1 and 2 and MAC Address 1 and 2. Since we are using Mobile Install more and more it would be very nice if the installers could document the network outlet in the same manner as serial number and MAC address and have this populated back to SI for reporting.
