scene variables in Houdini

hello,

is there a way to set environment variables when launching Houdini via prism?

right now we are using a custom launcher with shotgun which declares "PROJECT", "ASSET", "SEQUENCE" and "SHOT" environment variables which are converted to file variables when loading or creating a scene in Houdini via 123.py

I would love to be able to do the same in prism but haven't found how to set these yet (unless prism already has custom ones?)

thanks !

They already exist in prism.

['PRISM_SHOT', 'PRISM_USER', 'PRISM_FILE_VERSION', 'PRISM_ASSET', 'PRISM_CATEGORY', 'PRISMJOBLOCAL', 'PRISM_SEQUENCE', 'PRISMJOB', 'PRISM_STEP']

Not entirely sure why most of them have an underscore as divider, but some don't.
