White balance?

[calkinsc]

Greetings

I'm new to Sagelight, so this may be obvious, but in searching the blog and tutorials I haven't seen a description as to how, so I'll ask...

How does one set white balance in Sagelight? For instance, if I have a neutral gray card that I have imaged, and I want to set a white balance on other images based on the the gray card correction in the first image, is there a means to do so?

Thanks!
