Shortcode for registration if not logged in

Hi,

I’ve used the following shortcode on my Add Listing page to replace the standard “You must login first” :
[gd_add_listing show_login=”1″ login_msg=”Please use the links to login or register before adding your listing”]

I’m also using the usersWP plugin

If I click on the new Login link created with the above shortcode: it shows:
https://mysite.com/login/?redirect_to=https://mysite.com/add-listing/?listing_type=gd_place
Which is what I want so that after logging in the user is redirected to the correct Add Listing form.

The Register link shows:
https://mysite.com/register/
It does not include the: ?redirect_to=https://mysite.com/add-listing/?listing_type=gd_place

How do I change the shortcode to include the correct redirection after registration, the same as in the login link?

Many thanks
