Well, \offset would do exactly that if there were a single property of
OttavaBracket which represents its position fully.  The bracket's
final position is represented by Y-offset *and* something else.

It seems that OttavaBracket doesn't support the
line-spanner-interface, which means you can't directly set the
Y-coordinate of the endpoints.  This seems like an oversight.  I've
seen some slanted continuation lines, for example.

(N.B. \offset doesn't currently work with nested properties--like
'bound-details--but that would be a future goal for enhancement.)

Best,
David
