Dynamic Redirect after registration (can’t use Custom URL)

Hi,
I have set up a page as restricted to only logged in users and to redirect users to the connexion page if they are not. At this point, if they log in they get redirected to the original page and that’s perfect.

However, if it’s a new user and he makes a new registration, he will be redirected to his profile at the end of the registration.

I realize I can set a Custom URL to redirect at the end but that will only work for one page. What about when I have more?

Is there a way to redirect the new user to the last page he was at?

Thank you!
Pedro
