Dang. Thank you! Sorry for the long delay in getting back to you.
If I understand you correctly, is it possible for me to just boost the charge on that one cell instead of connecting every cell to an active balancer for the whole system?
Thank you!

Assuming that cell bank is good but it went out of balance because the battery was stored fully charged (that can happen), you can try to manually charge that cell to the same voltage level as the other banks. You need an adjustable power supply that supports CC and CV. Do not remove any connection to the BMS or it will get locked.
Also note that there are 13 strings in series, you only measured 12.
