Multiple "login redirect" pages?

I’m currently using the following code to redirect the user after login:

add_filter( 'wpmem_login_redirect', 'my_login_redirect', 10, 2 );
	function my_login_redirect( $redirect_to, $user_id ) {
		// return the url that the login should redirect to
		return 'http://www.domain.co.uk/page/';
	}

However I have created a second login page, and I want to redirect the user to a different page if they login here. How do I do this?

At functions.php level, WordPress doesn’t actually know what page the user is on right? This is from experience.

Is there a better way to acheive this?
