Can I change the icon in NetNewsWire Lite?

[18thTomorrow]

Hi,
I've started using NetNewsWire Lite for all of my RSS feeds, and I like it.
The only thing i don't like is the dock icon (yeah, I'm anal about such things )...sooo is there any way I can change that?
I know how to change "regular" icons, however this one functions like Apple's mail.app with a handy number-notification when I have new feeds. Is it possible to change this type of icon and what would it involve?

I changed my mail icon just like I changed other icons. Have you tried it?

the only icon that has problems when changing is the iCal icon.

you should be able to change it like any other icon without a problem.
