Combine same named objects

Also a lot of mesh modeling programs will have some function in them to break apart polygons that are in separate non touching chunks into separate objects.

In Cinema4D try selecting your combined object and then use the "Explode segments" command, in V10 it's on the menu under Structure > Edit Spline > Explode segments. After doing that it results in 3 separate sub-objects under the box so that may help you.
