Class mapping with attributes

[DSSPRAT]

I wanted to know if there is a way to not only map classes with a saved load file (under class/layer mapping), but to also assign attributes to these classes, i.e. line weights, colors, fill?

The main reason for this question is that we get updated civil files from our consultants on a regular basis on a large office mixed use development. Rather than take their file each time and redraw our site plan to have all curbs and parking aligned with civil and have our line weights/colors, I want to be able to take the civil and map their AutoCAD layers to our classes with the attributes we want.

If anyone has any other ideas how to handle this situation I would be interested to hear.
