Additionally, a Track Count, Disc Number/Count and/or Movement Count can be applied to each track, Episode ID can be configured with additional text incorporating the number, and zero-padding up to five digits can be applied. (The selected tracks must be sorted by ascending Play Order for accurate results.)
