I have an Apphome page with login & signup groups controlled by custom state to show/hide depending on which the user chooses (it’s login by default so whenever someone accesses Apphome, they see the login group first unless they click sign up button).
Send a url parameter to the next page. You can do this via the ‘go to page’ action (add a parameter). Your url then looks like this: https://mydomain.com?key=value
On the second page, run a workflow on page load with a conditional on the url parameter (do when get data from page url = ) and set the state here.
