There may be a workaround to achieve what you want without using LUTS, however we need to know what it is that you want to use a LUT for.

Basically to color grade, shooting in D-Log M (new DJI Mavic 2 drone) and I have several new LUTs specifically for this color space with this drone.
I used MEP Plus last year and I thought that I had found a way to be able to import / use LUTs. Maybe it was in another software I was using, I don't remember now...
