Ability to inherit personas and competitors from parent product or mass duplicate personas and competitors Merged

We need the ability to receive personas and competitors from a parent product/company/division because in most instances there will be much duplication and confusion if we allow it just per product. I would like this feature to function similarly to the custom fields where if there is a persona in the parent we could chose to enable inherit from parent that way if we wanted personas from the parent they would populate in the individual child product line.  Or maybe just be able to mass duplicate a persona(s) or competitor(s) into other products.
