Automatically remapped bitmaps

Is there a way to return the actual location of the bitmap file loaded rather than the location specified in the bitmap?

Not entirely sure how to phrase this other than to explain it the long way.

Let's say you have a scene file "object.max"
This scene file has an object "teapot01"
This object has a material with a bitmap in the diffuse slot "bitmap.png"
The bitmap is in a folder called "maps" in the same folder as the max file

This scene file was created a while back on an old computer. Now, residing on a new computer, the map is pointing to "c:\oldComputer\maps\bitmap.png"

Since the map is below the max file in the file structure, Max finds it and applies it wothout any fuss. Unfortunately, it's still pointing at "c:\oldComputer\maps\bitmap.png" rather than the file that has actually loaded "c:\newComputer\maps\bitmap.png"
