Callbacks during exec?

I started to drudge down the path of providing a "loading" progress bar to my project. Then I realized if in my torqueScript I am doing an exec of a resource, and that resource has x number of resources inside of it that its loading. How do I get a callback of what its doing? Is there some torque magic for accomplishing what I am attempting? Some way to evaluate the resource and determine the number of resources to expect? Or do people just feel comfortable saying I have levels, maps, fonts, etc, and just count the number of resource files they expect to load and increment based on that? Most professional games, you see the progress bars incrementing (or so it seems) on the actual loading of the resource itself.

any thoughts or help would be appreciated...
