Allow glissandi in double stops or chords

Double-stop glissandi or even chord glissandi are idiomatic in stringed instruments writing (both bowed and plucked), but as far as I've tried MuseScore only allows one note from each note group to be connected with a glissando line.
I always need to create extra parallel lines with the normal line tool.

Graphically, that works fine, but as the glissando line imediatelly sticks to the notes, allowing multiple parallel glissandi would save a lot of time.

Also allowing to change the distance between the glissando lines and noteheads in the glissando properties would be nice, as the lines sometimes override dots and accidentals.

Thank you very much!
