SNMPv3 - is it possible to send initial " get System description OID" WITH context parameter

Hi out there. I’m trying to model a bunch of Ricoh Printers with SNMPv3. They have a fixed SNMPv3 context of “GWNCS” configured. So I did a [SNMPv3 contexts to use in requests]-rule for them.

But when Check_MK tries to discover them, it sends the initial get sysObjectID.0 without context - resulting in no answer and the no sysOID error.

I can omit that with a [Hosts without system description OID]-rule. But is that the only possibility, or is there a way to tell Check_MK to send the initial get sysObjectID.0 WITH a context?

Thanks in advance
Bernhard
