Feature Suggestion: Shutdown Automatically

There is a nice feature in PortableApps to have an application Start Automatically when PortableApps starts.

I'd like to suggest a related feature: the option to have an automatically started app shutdown on PortableApps exit.

If it helps, I'm specifically thinking about KeyPass Portable. I have it start automatically and go to the system tray. I can always shut it down manually before exiting PortableApps, but it'd be nice to have it stop automatically.

[If this has been discussed before, I apologize. I did a search and didn't find anything.]
