Do you guys plan on letting us add a custom value to the default unsubscribe message?

We've built out our own custom unsubscribe page and automations, but the default one gets added as a duplicate but goes to the system unsubscribe page.

If we turn it off, our users will have to remember to add it to any emails in the automations so we'd like to have it added automatically, but be able to use our own confirmation page and links, etc.
