ISM slabs to RAM SS

I have created an ISM repository from Revit, and cannot create a RAM SS model with the slabs coming in.  Slabs show fine in the synchronizer and come into Concept fine, but I can't seem to get the slabs into RAM SS.  Any tips?

Edit: Never Mind, Just read the RAM SS documentation saying that what I wish to do is not possible.

Would a valid workflow be to use the ram revit link to create the RAM model, and then create the ism model from there?  I have a concrete pt parking ramp which has been modeled in Revit, and I need to start the design process using both SS and Concept.

Thanks
