It is easy to print multiple finger dots on the same string, but you will
need to use the verbose format if you want to use a predefined diagram.  The
terse format is limited to one fingering per string.

This is correctly done as a fret-diagram-terse string (note that there are
no string numbers).

This is a normal, rather than terse, fret diagram string.  Normal fret
diagram strings are not allowed as part of storePredefinedDiagram.  The
terse format does not include the string number.

Try the following:

\storePredefinedDiagram #default-fret-table
                        \patternB
                        #violinTuning
                        #'((open 4)
                           (open 3)
                           (place-fret 2 1 1)
                           (place-fret 1 2 3)
                           (place-fret 1 6 4))

This should work (but I haven't tested it).

HTH,
