Custom Chime Types on IQ4

Is there a way to customize the Chime Types for sensors? The built-in chimes are not pleasing to hear every time I open a door (considering they’re old Android alert tones). I’d love to be able to load my own if that’s possible. Does anyone have experience with that?

I’m one of the (many) defectors from the oncoming Nest Secure shutdown, and the one thing I miss are the pleasant chimes the Nest Guard unit made.

Customer chimes on the Qolsys panel is not an available feature at this time.
