How many units of Hyaluronidase does it usually take to dissolve 2cc of Voluma?

I had 2 cc voluma divided into both cheeks about a year ago. I hate the result and unfortunately I do not metabolize the filler fast so I don’t want to wait for it to go away. How many treatments of Hylenex would it take and what are the usual dosages you use in your practice? Diluted or not diluted? I would appreciate some guidance. I have only made small progress in few dissolving sittings so far and wondering if doses used by my injector are too small or too diluted. Thank you for advice !
