Hi Stephen,
I probably don't have the answer you're looking for, but with Blue Prism's (new-ish) Splunk integration, the session logs can be sent to Splunk and the Process that started the session comes in under the field name 'currprocessname'.
However, I'd also like to be able to retrieve the Process's Name from a VBO. Let us know here if you find that answer elsewhere. I don't know that I've asked Blue Prism about it specifically so there may be an easy answer.
Respectfully,
Dave
