I'm afraid there is not a way to do this, although a few folks have asked for it. I've gone ahead and added your name to that request, Kate. Perhaps the developers will add it in a future release. - Peg

Is there any way to save settings for each image, then? I'm working with about 30 flightlines and it seemed that the new viewer window in ENVI 5 allows me to load all the lines into a single window, like mosaickng, and adjust the stretches, brightness, etc. to get a good mosaicked image. I'd want to be able to save those settings, either to each individual file or at a project level so that I don't have to re-adjust the settings every time I open an image.

Is there a way to do it with IDL?
