How to change the default import settings for textures

Hi,

Whenever I import a texture it's bad quality. I want to change the default settings to Advanced and RGBA. Right now I change every texture that I import, but I was wondering if I can configure unity to import textures using these settings by default.

I found this link: http://answers.unity3d.com/questions/55118/changing-texture-import-default-settings.html, however it seems they are setting it programatically (I don't really understand how to use that code), I would just like to change the default values of the unity editor not change them when the games & scripts start running.

Edit: One idea that pops to mind is an editor script, but I wouldn't know how to approach this in an editor script... ideas?
