Audio clip, import, Inspector - default settings?

NOTE -- since about 2014, it's possible to select more than one AudioClip at the one time.

So, this is only of historic interest, fortunately...

You take a sound file, abc.wav, and drop it in your assets folder

Click on the file in the PROJECT panel, look at the INSPECTOR

You can change the values, LoadType etc. But they always begin with the values shown in the image here.

This hurts if you are dropping 100s of sounds in to your assets folder!

(1) is there a way to change the default shown in the image?

(2) is there any way to highlight 100 items in your PROJECT panel, and change the settings all at once?

(I looked on the asset store for a "mass changer," presumably an editor script, unfortunately could not find one.)

Thanks!

Later - I know nothing about editor scripting, but I cobbled this together. Please ignore my hideous c# ! This may help someone in the future ... cheers! You can very easily extend this to other properties in the AudioImporter, or indeed other importers.
