How to integrate user preferences

I have a 10-12 customer base for which i have their preferences in a plain txt file, Every time i run the crew i can pass the user id or name and the agent can pull up the corresponding file before taking any action so it knows the preferences.
How can i do that , is there any better or modular way to do that?
Any help is appreciated!

CrewAI recently introduced Knowledge. As stated in the docs:

Knowledge in CrewAI is a powerful system that allows AI agents to access and utilize external information sources during their tasks. Think of it as giving your agents a reference library they can consult while working.
