a program / command / script turing a lilypond full score into conductor's score and parts scores automatically

[Daryna Baikadamova]

Suppose if I typeset a full score (with all instruments that appear in the work) in lilypond, there are there any commands / programs / scripts that can automatically take the full score lilypond file and create pdf for:

conductor's score - with parts that do not play in a particular line in a system automatically removed to save space

parts score - with correct transposition and correctly replace continuous rests with a multiple-bar rest, or better, allow specification of length and the source (from which instrument the melody comes from) of hint as small notes before the instrument actually starts playing.

Are these features already there?  These features would greatly simplify the work of the typesetter and leave the mechanical works to lilypond.........
