Extracting (or separating) steel model out of AutoPIPE V8i Select back to STAAD

Hello all, I have a unique situation and wonder if the software has a solution.

We have a linked AutoPIPE V8i Select  /  STAAD PRO file.  Sometime after the STAAD steel model was integrated in to the AutoPIPE model, the original STAAD model was lost.  Is there a way to export the steel portion of the linked AutoPIPE model back to STAAD PRO.

Based on this thought process, I would also like to know if steel "originally" modeled in AutoPIPE can be transferred to STAAD as a new file; that they then can use / change / analyze?

Thanks.
