Writing automation coming from another track's CC

hi, I have a midi track sending some CC to another track’s VST. In the VST it controls a macro knob.
When I move the macro manually, cubase writes automation data for it, although the CC data from my other track moving the same knob isn’t written to the automation lane.
Is there a way to do this? Is it the VST’s decision to send back automation data or not, or is it somehow configurable in cubase?

(i done this so far: Midi routing / PLE / automation - hacking question)



Does it write the automation, if you send the MIDI data (to control the macro knob) to the VSTi from any HW MIDI controller (I mean from outside)?
