Way to return users to original URL post-password-reset, when the Login URL is dynamic

Just checking, is there a way to dynamically set all or part of the Application Login URI? Our application might be accessed at a.place.com, b.place.com, and c.place.com. When a user resets their password we’d like them to see a button allowing them to return to the url that they originally tried to log in to. I’ve seen this post and these docs, and wanted to pick your brain(s) for a way to achieve the desired functionality.

Hi,
You could set up a Configure Default Login Routes per application…basically then when a user resets their password at different URLs you can customize the return URL to match where they originally tried to log in.
