Tvheadend

I have tvheadend running on synology NAS (4 DVB-T tuners) and a Raspberry PI (LibreElec with 1 DVB-S tuner). Using my WDTV box I can see files as soon as they are created on the respective shared folder. I have confirmed that with a 90 second delay to starting the playback I can watch what is effectively a timeshift of a recorded program. What I would like to have is a recording profile that can overwrite the created file, this would allow me to have as an example stream.ts as my filename which I then could playback from the WDTV (and possibly other devices). It would effectively provide the same function as the play option but allow a different device to receive and show the stream. It would certainly be a useful function to allow IPTV streams to be directly played.
