Hello, I am looking into ZeroMQ and I wanted to ask if all the other variables/fields can be input externally such as the SessionName [N] etc. not just the primary ones listed in the documentation.

I am creating an external app that controls triggerboxes, lighting, live-webcams etc for our multi-camera scanning rig, and I was wondering if I could control the session naming from this app and send it to CaptureGrid through a python script.

I.e. generated name internally in my app → export it to CG4 as the PhotoSessionName variable before shooting with my triggerboxes. Or is the PhotoSessionName only for the listener?

Thank you!
