Can Application Builder pass varible value to VI

I use application builder to make two executables that are built from the same VI.  The only difference is the value of a boolean variable in the VI.  In one exe the boolean in the VI is set to true, in the other exe the boolean is false.  Currently I have to change the value in between doing the two builds.  Does anyone know of a better way to do this?

I've used defines in C language compiler projects to control things like this.  I haven't run across anything like this in Labview.

Thanks for any suggestions.
