Ability to create a variable for a filter and prompt to fill in

Allow the ability to save a filter without the full parameters set. Our team has a use case where we want to be able to quickly filter by an application so if we could have it auto save "where application is ______ and just not fill out the Application. Then when a person goes to the filter they can determine what selection they need on that given day.
It would also be awesome if when you go to that view, it would prompt you right away to say “update your selection criteria”.
