as a PRTG user I want to see which switchports are already monitored when I add new ports in the SNMP Traffic Assistant.
Details of User Story
Scenario: Network switch with many ports, some of them are already monitored by SNMP traffic sensor. Now a bunch of new ports goes online. With the current GUI of adding an SNMP traffic sensor you see which ports are connected or not connected, but you don't see, which ports already have a sensor placed on or not. So the customer has to manually check his documentation which ports are already covered by a sensor.
Another column in the "add sensor GUI" indicating that a sensor is already placed on ports.
