I imagine an app_info could be written to do what you want, though I've never been smart enough to write one...for any project for that matter. I've always done a deep dive into the project forums to see if I could find one that is already written. You might want to spend some time at WCG to see if you could find something that would work for you or could be easily adjusted to work. You're right, it would make it so much easier if they had separated OP into 2 projects, cpu and gpu. Do you have the capability to run multiple instances? If so, doing what you want would be relatively simple I would think.
