Ram Concept - Export Reactions to Mat Slab

I'm modeling a building that has several stories of two way P-T slabs with a mat foundation. I've modeled/designed the P-T floors in RAM Concept and am looking to use Concept to design the mat foundation as well. Is the intended workflow to completely finish the P-T design in Concept, then export all of those floors to RAM SS? Then after bringing it into RAM SS, re-export my loads back to Concept so that I can design the mat slab there? This seems a bit of a roundabout manner of doing things but its seems like maybe the way to go. Also, if things end up changing in my P-T floors after I've done the export loop once, what is the best way to make sure my mat foundation loads get updated in Concept?
