If you have all of Camera 1’s shots on V1 and all of Camera 2’s shots on V2, you should be able to do this as long as they are synced at this point.
What I would do is hide the V2 track and export V1 as it’s own clip. Then Hide V1 and export V2 as it’s own clip. Import the two clips and sync them as you would any other multi-clip using the in as your sync point.
