Save a stream opened via 'Advanced' -> 'Open Stream' in iTunes 7?

Hi Gang...first post here...'switcher' to an iMac as of last week.

In iTunes 7, if I open a stream via the 'Advanced' menu and 'Open Stream,' can I save that as a bookmark or something similar so that I don't have to type in the URL everytime I want to listen?

Thanks much for the help
Mike
