Overlay VIDEO but retain existing AUDIO
It would be very helpful to have an OVERLAY VIDEO function, with the OPTION of using the audio in the video, or the underlying AUDIO track. This would facilitate video in/out bumpers, animated logo transitions, etc.) that preserve the underlying audio recordings. (This can already be done with the "Overlay Image" function - which preserves the underlying audio - but that is a static image. The ability to overlay a video and keep the underlying audio would be a solid addition to the software.
