Split stem for augmented and diminished unisons

[bel28kent]

Is it possible to add split stems for augmented and diminished unisons?

Here are two examples from Scriabin, Deux Poèmes, Op. 71, No. 1. The first is in m. 3 and the second in m. 7.

Here is how they render in VHV currently.

Is this possible @rettinghaus? I seem to remember you discussing it somewhere (but don't remember that it was ever implemented).
