Simplifying Subscriber Preferences Without Login Access

Hey everyone! Quick question: I created a subscriber preference for my Wednesday newsletter. By default, all subscribers get both Sunday and Wednesday issues. Now I want to offer a simple 1-click opt-out just for the Wednesday email – without unsubscribing entirely. The problem: When users click the “email settings” link, they have to log in via Magic Link to access the preferences. If they’re not logged in, they only see the full unsubscribe option. 👉 Is there any way to let subscribers update a specific preference (like a custom field) without logging in? Thanks a lot!
