Enabling redirect_to when using default login page?

I'm using the default FC login page for my site which is hosted using the domain (no /portal or other path). No page within the site is visible to non-logged in users. I'd like to be able to share links to spaces and other pages and have users be redirected to those space links or pages after logging in.

I've done this before with custom login pages using the redirect_to functionality. I see in the code that it looks like this would work but only if using a custom authentication page instead of the default.

Question: Can the use of redirect_to be expanded to work with the built-in default authentication page? If not, is there another way to redirect to the original URL after logging in?

Thanks.
