We have a project for the implementation of Zoho CRM in a small company. We have a mutlti department segmentation. It means that a customer (an account) can get several Account owners. 

The only (bad) solution seems to clone all accounts :

Customer 1 / Account 1 - Account manager 1

Customer 1 / Account 1 - Account manager 2

Do you see a more efficient solution to handle that ?

Maybe by using the Mother Company ?

Mother Company

--- Customer 1 / Account 1 - Account manager 1

Thank you.
