Question about half dim chords

Hi all,

Just to know, is it possible to have iReal kernel play the correct half dim chord.
As you know in major system CØ comes with b9 and 6b but we have different feelings CØ9 (melodic minor) or CØ13 (for harmonic minor). It comes that iReal does not play the corrent scale/chord relations at piano comp or bass line.
My solution now id to put a minor chord with its 6th at bass. It looks the system does not play any 9th or 13th but it sounds very clean.

Grazie,
Gatto.
