Any way to get bounding box for all parts of an assembly?

I am importing assemblies from Iges.  They are flat (no subassemblies).  I need to get bounding box information so I can sort by thickness.  The bounding box isn't going to need to be update.

Is there any way to open an imported assembly and slap out the bounding boxes for every part - without opening each part?

Thank you,

Todd
