Separating many objects?

Hi all:

I have a problem with a client's STEP file of their product, coming from Solidworks.
It's a complex product, with over 300-pieces, however, the way that it was exported NONE of the parts have unique names / tags / ID's etc. Therefore, when I import the piece into MOI, it's just one single object. When I click on that single object name in the browser window, it does indicate the total number of objects in the model. So...is there anyway that I can have MOI "explode" the pieces so that each has a unique name or layer, so that I don't have to click select one-by-one for hundreds of parts?

Thanks!
