We had a discussion about this in another thread and there is a tutorial available for using 2 cameras. (Link below).
Keeping synchronisation during editing is the challenge.
If you have 3 synchronised tracks, create a 4th to be used for the active camera. Use track 3 for the main view.
Copy the required sections from tracks 1 & 2 up to the top track.
The bottom 2 tracks can be hidden before exporting.
