Stop auto-started apps when PortableApps closes?

I've got a few apps set up to auto-start when I run PortableApps, and I'd like them to automatically stop when I stop PA or hit its eject button.

I found a few threads here, but they all seem to lead to defunct apps like AutoClose (https://portableapps.com/node/20900), so there doesn't seem to be anything active any more. Is there a way to do this? Or something in the works?
