That's an interesting approach to building a robust Business Manager. While directly inserting a personal ad account might seem like a quick fix consider the potential complications. A personal ad account is inherently tied to you as an individual. Moving it into a BM could create ownership conflicts or limit your ability to manage it independently later. A better strategy might be to create a new ad account directly within the Business Manager. This ensures clear ownership and simplifies long-term management. You could then transfer relevant campaign data or learnings from the personal account to the new one. This keeps everything streamlined and avoids potential policy issues related to ownership. Think about how you want your business structured for the future and choose the path that supports that growth.
