RAM Foundation to RAM concept for combine footing

Question

Hello All, 
 
 I am currently looking into designing a foundation of the shear wall which is at the basement level and at the end of the wall there are two gravity columns. 
 My intention at the end is to pick those gravity columns in the foundation of the shear wall to have a combined footing. 
 I designed individual foundation for Shear wall and Gravity columns in RAM foundation, but now I want to combine them and see how things move forward from here. 
 
 The option I was able to establish was using RAM concept for designing a combined footing. 
 
 While transferring the RAM SS file to RAM concept I am having some trouble. 
 I first tried using RAM concept > Import from RAM SS file. 
 but when I am importing a file it shows only few foundations i.e. just Shear wall and not gravity column foundations. 
 Good thing I tried making ISM repository of RAM SS and imported into RAM concept and I was able to see all foundations, but RAM concept just allows a story to be imported. Cant I import the entire structure using repository? if yes how? I tried importing another story after importing one, but gives some error. 
 
 The best option here would be If I can transfer the entire RAM SS model to the RAM concept. 
 I am wondering if I can simply replicate the entire model of RAM SS to RAM concept and then I can check the reactions at the base of it in both RAM SS and RAM concept to see they are same or No. 
 and then design a combined foundation. 
 
 Any other Idea to workout combined footing is really appreciated. 
 Thanks in Advance.

Here's what you want to do. 
 
 Model a mat foundation in Ram Modeler (on the lowest framed level type). The mat needs to be big enough to encompass all the supported walls and columns. It needs a "Deck" property to be assigned. The elevation can be adjusted, but that's not a requirement. 
 Rerun the analysis (Ram Frame, Ram Concrete) 
 Open Concept and import the Mat (or Launch Ram Concept from the Ram Manager). 
 
 For more details on the import see: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/4334/ram-concept-ram-structural-system-integration-tn 
 Note, if the columns and wall are integral, then I would make them all lateral. I assume that they are all Concrete, but be aware that for steel columns on a mat, only the loads, not the actual columns, come into Concept.
