P: (Masking) "White Balance Background"

[gribfib]

Sample problem: You've used a daylight-balanced flash in an indoor tungsten environment. If you white balance for your foreground subject, the background color will be off, and vice-versa. Currently you can 1) select the subjet, 2) invert so that the background is selected, and then 3) "eyeball" proper white balance. But this is inexact. 

Requested feature: Within the Masking module, have a "White Balance Background" selection option that automatically selects the background (steps 1 and 2 above) and presents an eydropper tool for white balance. Much faster!

Everyone has their own favorite feature, but the mask panel would become utterly cluttered and confusing if all these features were honoured, so I would not vote for this request. What I do agree however is that there should be an eyedropper tool to correct the white balance in a masked area.
