Changing an App path

Hello, I did a little search here and couldn't find what I am looking for, so here it is.

I got this Firebird language extension installed. But in order to activate it, I gotta use a shortcut using the -UILocale thing at the end, and it works perfectly.
But now there it is, from the PApps menu I can't open the shortcut, even if I rename it to the same name as the usual .exe file...if there was only a way to change the path to my shortcut, it would be perfect.

Thanks in advance
