Multi Stl snappyHexMesh

I am trying to mesh a geometry with 3 regions ( inlet, porous and outlet). I have 3 closed stl's for all the 3 regions in the triSurface dictionary. When I write the snappyHexMeshDict ( with inspiration from the multi region meshing in chtmultiregionfoam), I define the stls as faceZone and CellZone.
When snappy runs, it detects these face zone and "walks through them" and meshes both inside and outside the pipe ( all 3 regions). When I comment out the faceZone option, it meshes only in the region where the locationInMesh is found.
After some thought, I realized that it might help making the closed surfaces which are the interfaces btween the different stls as faceZone and then let snappy just walk through them build the mesh, theoretically. Unfortunately, that doesn't happen
Is there a better way to do this. In simple words, how to mesh for an internal flow geometry with closed stls by multi region approach using snappyHexMesh.
Hope I was clear.

I am working on the same topic to " Mesh Stl files in SnappyHexMesh to get internal faces".. if you have proceeded any further.. Kindly provide the details..
Thanks in advance.
Thanks & regards

I am also having the exact same issue as you Kalyan. I also posted in this thread referencing this problem.
Does anyone have an explanation as to why what Kalyan describes is happening?
