Auto populate contacts in Opportunities

Hi,

I am using the default configuration of SuiteCRM for accounts/contacts/opportunities.

  1. I created an account account_test
  2. I created a contact and I linked it to account_test
  3. I created an opportunity and linked it to account_test

When I am inside the opportunity that I created, we have a “Contact” subpanel but it is empty. How can I do to auto-populate this subpanel with all the contacts linked to account_test ? Tell me if I’am not clear.

In brief, I want to auto populate the “Contact” subpanel of an opportunity with all the contacts who are related to the corresponding account.

Thanks.
