Copilot Agent ALM and Knowledge Source Management Across Environments

Hello everyone,

I currently have an agent in a Dev environment and want to deploy it to a second environment (e.g., Test or Prod). 

During deployment, we need to change the references to the knowledge sources. I’ve seen some articles where environment variables are used within Conversational Boosting topics to handle this, but I wanted to check if there is a supported or recommended way to manage or update knowledge source references from the Knowledge section itself to make them dynamic by using Environment variable?
Any guidance or best practices would help. Thankyou.
