Oh, I understand what you're asking. No, you cannot select "Sheet" as an option in the View Type because a sheet itself does not refer to anything. A sheet is simply the means to show a view in a printed or other presentation format.
Why do you want to refer to a sheet? In other words, what do you want to accomplish by referring to a sheet? The view reference family will automatically show the sheet number of the view you are referring to, but a view reference can only refer to one view, it cannot refer to multiple views, and a sheet commonly includes multiple views.
