2 Views at the same time

Would it be possible to have 2 Views at the same time(For example, F2 views and F1 at the same time, side by side). I've seen someone made it using 2 different video, but it's not perfectly synced. It would be cool for content creator to record the cab and the cabin at the same time.

related: render camera view to reindexable texture buffers (ex. cab mounted cctv, single index for each monitor, reindex texture's camera POI by proximity).
