Analyst agent in Microsoft 365 Copilot

I would like to ask when the Analyst model will be made available for creating agents within the Copilot M365 app. Currently, it is not possible to select Analyst as a model during agent creation. Having this option would be extremely useful for building custom agents with a preloaded Knowledge Base, rather than the current one-shot approach where files must be uploaded each time. This capability would greatly enhance data analysis workflows. Thank you for your attention, and I look forward to your feedback
