virtual inputs?

Hello,
I’m using the latest version of Reason and they now have an external MIDI instrument device that allows the user to connect to soft synths/samplers or hardware synths. I’ve seen this done with Kontakt - Kontakt has multiple virtual inputs which then Reason can see and trigger. Does the HALion 4 sampler have something like that? It would be cool to trigger the HALion from Reason.
Thanks,
