Add printer, IP phone, network switch as a inventory

Hi All,

I would like to add the printer, ip phone, network switch, etc as a inventory to manage. I know I can't manage those devices actually, the purpose to doing this is for reporting only.

When I add the device on the console manaually, I can select the type of device to other, but when I saved to finish adding, the type of device switch back to "Computer". How can I keep the type of device as other?
