stop auto changing color matrix

[gratevideo23]

When I load a video in Hybrid, is there a way to make it ignore trying to automatically change the color matrix?  for example, I am importing a prores file in rec2020, but its resolution is small, and hybrid is setting it to rec601.  I want it to stay at rec2020 and just be able to encode the file as h264 or h265 but keep rec2020.
