Unfortunately it seems to confirm the problem that there is no way to set white balance other than the Default presets. And it seems that there is no easy way in resolve to correct white balance.
My workflow is to shoot with the closest WB preset, and do a pre-grade in resolve with LUT and White Blance using seperate RGB curves/gain before it goes to the editor.
If the white balance issue is solved and the editor can use LUT's it would save the time of the pregrade and all the extra data involved.
If people have ideas on better workflows to deal with the situation I'm curious to hear them.
