Archive Old Pages - not just unhost

I have unhosted pages that I am no longer using but would like to keep to potentially reuse again and for historical value (although I'm not sure if there is any value there).

My request is that on a Campaign Trigger "Fills out Form", if you could only list the forms that are hosted not all of them that would be great.

My thought is if there is a way to "archive" pages, not just unhost them then when the "Fills out form" list come up, it doesn't include the "archived" pages.

Thanks for considering!
