Differentiate autostart by PC

The autostart feature is a usefull thing, but I need an advanced autostart that can start a program, when the PortableApps is run, only on a specific PC.

I want to make a programm autostart only on a specific list of pcs (1 or more), but not on all of the pcs that I use with my usb.

Can this be done? Is there an alternative available (other than the existing autostart)?
