artist words in pattern

[modul]

create artistsplit[] in arranger initialization.
use in rename pattern: {artist1} {artist3} etc.
what to do when words in pattern exceeds length of artistsplit[]?

user should put it in another pattern, using it only when he knows, what artist it'll be used on. like:
[singer-pattern]
newpath={artist2}, {artist}/{album}/{title}

The {initial} must have the same functionality:
{initial2} == first letter of second artist word. so:

[singer-pattern]
newpath = {initial2}/{artist2}, {artist1}/{album}/{title}
