Tvheadend

Hi. I’m using Schedules Direct (SD) on Vero 4k with App Store version of tvheadend in UK. I prefer how SD organises programme data and displays it on Kodi epg (plot info isn’t duplicated in programme title as well as plot description) which I understand is being fixed for OTA grabbers in version 4.4. However, I prefer OTA grabbers for accurate recordings when there are schedule changes. Is it possible to use SD as the epg source for all channels, but have OTA grabbers as a higher priority to better handle schedule changes? Would the OTA grabbers overwrite SD data in this scenario? Thanks.
