What is the best way to edit [jbp-expert-update-page]?

Is there a way to edit [jbp-expert-update-page] that will not conflict with future updates?
My goal is to redirect users not logged in to a front page registration/login page and not to http://www.wordpress-install.com/wp-login.php?action=register. I simply need to revise the link: "wp-login.php?action=register" to the new login page.
I realize that I can do this with Membership 2 Pro, but I would like to use a different plugin.
Thanks!
