Yes.  What we'd need is a dash-fraction and dash-period property
instead, see text-spanner.

However, for dashed/dotted slurs to be really nice, the current
builtin postscript dashing is too simplistic.  The path length of the
slur (and text-spanner) should be taken into account to make sure that
begin and end are solid, ie, the slur (or line-) ending must never be
part of a gap.

What is it exactly that you need to know.  What do you miss when
looking at the places where a property (say dashed) is used?
