Skipping non-MVS shifts in book-off

Individual non-MVS shifts can be booked off in Details Edit mode. However, they are not supported in Mass Edit or the Book Off action in ASV until they are silently converted to MVS shifts. In the Book Off action, if a user selects a time range for booking time off in which unconverted non-MVS shifts occur, the non-MVS shifts are not booked off.
