Sigma Studio Options for "Post-export command"

I would like to use the "Post-Export command" feature.

Are there any options I can include in the command line like the name of the currently open project?

For example, I'd like to create a command like the following psudocode...

MyPostProg %p

where %p should be expanded into the name of the project that is being exported.

Maybe $p or some other parameter replacement.

Thanks, Mark
