Trying to create a "partial preset"
I'm trying to modify a .prfpset file, (of .r3d source settings) to NOT USE any values for Kelvin, Tint, and ISO. I want these values to remain the same as they were BEFORE the preset is applied to a clip.

I've found the exact location(s) where I need to make this change. I just don't know what character(s) to put here! I've tried:
0
""
X
<CurrentValue>
<>
null
none
*
But, either the preset will refuse to import, or the value will be set to the lowest possible value. Does anyone know the correct text to use here?
Or, is there ANY way to specify that I DON'T want a specific value to change, when a preset is applied?
(Here's the long version: Taran is distraught over color grading .R3D footage in Premiere - YouTube )
