Are there Image Analysis Window Environment Settings? (ArcGIS 10)

I am enjoying the speed of data processing with the Image Analysis window, but I don't like that the processing settings aren't transparent. Is there a way to set the Raster Analysis Environment Settings and have them be honored by the analysis window? the most important ones for me are during mosaicking, I'd like to be able to define a cell size (it always defaults to minimum of the mosaicked data) and I'd like to be able to specify bilinear interpolation as a resampling technique. But regardless, it seems like the environment settings should be honored by the image analysis window.

Hi Andy,

For of the Image Analysis window, the input layers take precedence over the default ArcMap settings. So if you change your input layer with contrast and brightness, and then clip (for example), then the clip will also have these contrast and brightness settings. These settings come from the top layer in the layer list. I think this is done to preserve the changes you have done to the layer.
Regarding the resampling technique, this is done through display resampling at this point. Note that you can easily change the mosaic method (min, max, blend) even after the new layer is created by simply selecting the new layer and then changing the mosaic method on the image analysis window.
I hope this helps.

What I can't figure out is how to control the resulting image resolution. If I mosaic a series of grids, and one has 50cm resolution, the output mosaic has 50cm resolution. I'd like to figure out how to mosaic and have my output resolution set in one step. Anybody know if that's possible using the Image Analysis Window?
