Can you dissolve lip fillers only partially on one side or does it dissolve everything?

My upper lip is uneven after lip fillers. (This is very frustrating as the reason I got them filled was to correct asymmetry and now the asymmetry is even more apparent.) I would like to shrink the larger side, but don’t want all the filler to just go to waste. It would be a huge waste of money and time. My question is: Can you have lip injections only partially dissolved on one side? Or does injecting the dissolvent just dissolve everything.
