Wireshark · Wireshark-dev: [Wireshark-dev] Subdissector with multiple selection fields needed?

[Weston Schmidt <Weston_Schmidt@xxxxxxxxxxx>]

I've got a protocol that I'm dissecting that has 3 fields that define which subdissector should be called.  How should I enable the selection in a 'Wireshark' friendly way?

3 Fields I need to merge into 1 for sub-dissector selection purposes:
EISS
org_id (4 bytes)
app_id (2 bytes)
trigger_table_id (2 bytes)

Thanks,
Wes
