Automatically copy selected music to drive on Synology eSata port

I realize this is going to come off as a strange question but is there a way to create a script or other solution that would allow a track or album which was selected to be played (from my Synology hard drives) and first have it copied to a drive on my eSata port to then automatically have it played from that external drive?

Roon runs on a Synology DS918+ and the music is stored on that device as well.

Thanks in advance for your suggestions.
