ISM Footings

I'm trying to bring a RAM SS model into Revit, and while I appreciate the new options regarding materials and deck mappings, I'm struggling with my foundations coming in correctly. 

I want my RAM Spread footings to come in as a a family type "Footing" not "Foundation Slab".  Is there any way to manipulate the ISM file through the editor, prior to Revit import to make this happen?  Columns and beams can create new types of families, so I'm not sure why footings do not the do the same. Am I just stuck with Foundation Slabs under all of my columns that I have to manually change to Footings?


Thanks,
