Transcriptions and user roles

Hi, I recently started using AI Engine, and I must say it’s a fantastic plugin! I’m considering purchasing the pro version to integrate assistants. I wanted to ask a couple of things:

• Since I have already set up assistants in OpenAI and have a playground with thousands of transcriptions from my videos, is there a way to upload this content to AI Engine? Or can the assistant I configure in the plugin already work with this content?
• Another important question: I need to differentiate my assistants based on the role of the logged-in user on my site. Is this possible?
  
  Thanks
