CTAnt+ on a computrainer or Perfpro

I looked around and can’t get a definitive answer on this

Can I use CtAnt+ to read from my Quarq and adjust the resistance of the CT based on the Quarq reading (in Erg mode) ?

I believe Perfpro allows to read from the Quarq when using the CT but it doesn’t feed it back to the CT in Erg mode. Is this correct ?

I want to use the CT in Erg mode but if I say “hold me at 200 watts”, I want 200 watts measured by the Quarq.
