Trying to import source files and OCIO file into RV and then transition to Screening Room using Python

Hey there!
Sorry for the very confusing title :sweat_smile:
But I’ve been trying to import source files into RV using Python, I got this part to work by using subprocess
rvpushpath = "C:\Program Files\Shotgun\RV-7.2.6\bin\rvpush.exe"[rvpushpath, 'merge', version_path])[rvpushpath, 'merge', ver_zero_path])[rvpushpath, 'merge', prev_path])

Now, I want to know if I can do the same thing for importing an OCIO file, if not, how do I import an OCIO file into RV?
Also, after loading all of this data/files into RV, I want to then open this session in Screening Room. Would it be possible to do this in Python?

Again, so sorry for this confusing post but any help regarding this would be very appreciated!
