Hi Greg,
Historically, we haven't ever had presets for specific Kelvin in our controlling systems. However, this is something that may become available in a future firmware update to the Director.
If you are looking for a 20K spectrum for the 52, would recommend a 1:2 Ratio of White to Royal/Deep Blue on the lights. The other colors can be adjusted as you wish and won't have a dramatic difference on the color temperatures, however, would recommend keeping them at or lower of that of the White Channel.
