Create button in pop up that updates field

I would like to create a button in a pop up when clicked updates a field value is updated

One of my users complains about the number of taps it takes for him to get into an edit form just to update a single field marking that he's re-visited that feature. This is a neat idea to have an option to configure a button in the pop-up that could just update a single field with a specified value.
