Upload external fingerprint from DB to Adafruit Fingerprint Sensor

I am trying to upload an external fingerprint from my DB to the Adafruit Fingerprint Sensor. I want to know if someone has managed to do this and how. I've been working with this for a while and i've managed to register a fingerprint and upload it to an external DB. Now i want to do the next step, trying to save that fingerprint already enrolled into another module. So i can have a reception/door system, in order to make it work as if it were an hotel for example.

Thanks in advance to anyone that can help me with this problem. :)
