[Plugin: WP No External Links] Only selected URLs to be masked?

I have some links:

http:/awin.com/bla

Then some banners

http://awin/banner-bla

The banner links I wouldn’t want to be redirected but the other links I do.

Is there a way to control some links from being masked, and others not.

Thanks
