adjusting the settings for multiple assets

hey guys . when importing assets into unity, is it possible to adjust the setting of multiple images at ones for example?

There's an editor script on the Unity Wiki which allows you to do this:

Unity Wiki - Texture Import Settings

I've posted an editor window script once to do it while importing (or reimporting) the assets...

I've lately been working on updating it actually, so if you need it, drop me a line and i'll try and give you an updated version I'm using at work.
