We would like to show what DEALS are attached to an account on ALL Contact records for the Account.

Can we show this somehow using CRM Canvas tool?

I know you can assign a Deal to multiple contacts on the account but we don't want to make our sales team have to remember to add all existing Deals to a new contact OR remember when creating a deal to assign it to all account contacts.

I assume there must be a way to display the Parent Account Deals on a Contact somehow?
