finger stroke position

[pabuhr]

Is it possible to make the left bar look like the right bar below?

Specifically, there is a clash with the triple number even though I specified:

   StrokeFinger #'add-stem-support = ##t

and I would like the finger strokes to lineup vertically rather than following
the note height.

Using markup is a hack because the distance between notes can change and then
the spacing in the markup has to be manually adjusted.
