Open from tethered

Hi everyone, I’m hoping someone can help with this. I’m tethering my Fuji xt2 to my windows laptop using the Fujifilm tether app. If I point the files to rawtherapee.exe it automatically opens which is exactly what I want.
Can I do this but not open a new instance of rawtherapee each time. What I want is that each time I take an image, it pops up in the develop window of rawtherapee?
Cheers.

Have a look at Command-Line Options - RawPedia especially -R

I also shoot Fuji, but hadn’t considered using the tether app with RawTherapee. I will definitely look into this!
