Declare new tab or window in URL/PAGE tag

Is it possible?

If not, how can I edit the default URL and PAGE tags to add another parameter to open a new tag or window?

I haven't tried any parameters. Maybe one already exists? The Comcode tag assistant or the docs don't show any support for opening these tags in new tabs or windows.

Well this is embarrassing.

Guess I should've tried that before posting
