Recording events from Midi Device Panel

Hi! I want to send Sysex messages for triggering pattern changes on a drum machine. To simplify the creation of the Sysex messages for different pattern requests, I created a MIDI device, a corresponding parameter for the Sysex creation, and a small panel for selecting the pattern and triggering the Sysex send.

This works well: when changing the data entry on the panel a Sysex is being sent, and the drum machine changes pattern, but now to the question: I have found no way in Cubase to record the generated Sysex. This is reasonable, since it is the output of the track, and not the input. My workaround is to use a MIDI loopback pair (finally native available in Windows) for routing back the output to the input of the track (MIDI thru is disabled for Sysex).

  1. Is there a way to accomplish this within Cubase, without the use of external loopback or routing programs?
  2. Is it possible to use the parameters, e.g. PatternChangeTR8S in the figure below, directly, without assigning panel elements to them. Like MIDI CC or automation?

Thanks!
