Is it possible to use nest in a multiclip?

Hey Gang,
I an editing a music video. We had 5 locations, and I used multi-clipped editing for all the shots from each location, to select out the best.
I have collapsed the multi-clips, which now appear as Sequences. I have also opened those sequences and nested the clips.
Is there a way to use the collapsed multi-clips or nest to make a new multi-clip, so that I may edit the whole thing like a multi-clip(in one pass)?

Thanks for any help.
