Opening an account after became BCBA

I previously created my Ripley account as a supervisee while accruing BCBA fieldwork hours. I am now a BCBA and will be supervising trainees after a year passed. I would like to use my existing account as a Supervisor while preserving all of my historical fieldwork records. Can my existing account be converted to or provided Supervisor access, or do I need a separate Supervisor account?
Thanks in advance
