How can i jump 20 or 50 Tracks forward?

[Florian1975]

How can I jump 20 or 50 tracks forward in an audiobook? I have already tried the commands "20 tracks forward", "forward 20 tracks" and "jump to track number 20". Everything doesn’t work.
I can only jump forward one at a time. With over 400 titles, however, this does not make sense.

Thanks for help
