Is there any way to share a product on more than one plan?

Hi everyone!

We are using demand planning for a short period of time. As an initial strategy, we decided to use a plan for each business, as we understand that it has different characteristics and that there would be a benefit. However, because of the pandemic, the organization decided to share some products between the companies. So, theoretically, I would have 1 product that should be in 2 plans and each plan would have a different history. Has anyone ever had this need and managed to get around? Or the suggestion would be to unify all businesses in a single demand plan.
