Working Directory Woes

Is there an option, configuration file I can add, or something coming in a future release that will allow me to set a working directory for an application that wasn't installed using a paf.exe installer?

I have an application or two that run perfectly from portable devices, but I can't run them through PortableAppsMenu because it apparently runs the applications using the PortableAppsMenu as the working directory.

I am not really interested, nor do I have the time, to create an installer. I would just like to be able to assign a working directory to a menu item.

At anyrate, I have fallen in love with PortableAppsMenu, but do need to get things working easily.
