Artificial harmonics

Is there a way to notate them for durations <= to the quarter note?
What I need is a black ordinary notehead plus an open diamond let's say a fifth upper, at the same time.
More generally, I understand that including other fonts for noteheads is a hard stuff, but would it be at least possible to use all the noteheads in a duration-agnostic way (e.g. the open triangle on quarter notes)?

Thanks!
