S/N detection for removable media channel

Currently we can define on Data Security on the Resources->Endpoint Devices a "device name" for the removable media. This option is not enough, since we can only define a name of some very large number of USB devices, and not serial numbers. We would like to see an option on Websense DLP that will allow to define a list of trusted USB stick Serial Numbers and a list of local USB printers SNs.
