[feature] Add token to get updated URL after browser steps change the page

Is your feature request related to a problem? Please describe.
It would make my workflow easier if I can directly go the new page from the notification I receive.

Describe the solution you'd like
Add a token that contains the URL of the final page after browser steps have been completed. (the same page that the filters are performed on)

Describe the use-case and give concrete real-world examples
I have a monitor set up that goes to the home page of a site and then some browser steps to login and click on the latest article, it then runs a filter to gather some of the text on that page (the article's page). I send I notification when the text has changed (either updated the article or they added a newer entry to the homepage). On the notification, I send {{watch_url}}, however this token points to the homepage, not the page where the filtering is actually done.

Please let me know if this isn't clear or more details are needed. Thanks

nice idea!

This is also handy in the case generally when a page redirects even if you're not using browser-steps because sites can redirect etc
