Hope to have real l.v. ties

When dealing with piano or harp scores with lots of l.v. ties, there's a problem. When there's a chord with l.v. ties, every note should have a hanging tie. However, Musescore doesn't alow us to enter ties to nowhere like we do in Sibelius, while the let ring articulation only gives one curve on the whole chord. Therefore, we have to enter hidden note or chord to let the ties work, which both confuse braille transcription and bring more work to engravers. Hope the future Musescore can allow non-destinated ties or a real l.v. tie for note and chord. L.V. tie is implemented in Musicxml, although the current l.v. articulation can be exported correctly (fixed issue 298080), this is only a workaround for braille transcription, not real publishing. Another kind of solution is to let the let ring articulation automatically display multiple curves according to note amount.
