I am trying to write a connector to poll a device using SNMP v3 and I need to pass a different contextName value in the get request in order to access different parts of the MIB from a common IP address. Unfortunately I can't seem to find anyway in the connector documentation to specify the contextName in the SNMP request. A wireshark capture shows that DataMiner is just sending a blank or missing value for that field in the packet.

Is there anyway of specifying the contextName to be used?
Ideally I would like to to be able to change it dynamically, (similar to how you can change the community string value used in an SNMP v1/v2 connector by using a parameter with the <SNMP options="GetCommunity:0"> tag)
