Opening in a different tab/window happens in a different part of the process, and isn’t covered by this plugin.
If you know which URLs will redirect to pages you want to end up in a new window, then you can affix the appropriate markup to the original URL where it exists on your site.
If I have a link in my about page that redirects, but I want it to go to a new window, I make it open in a new window first, and then the redirect happens.
So, it is not possible with this plugin; it isn’t what it does. Please mark this thread as resolved.
