Role based security & sales territory restrictions

Role based security & sales territory restrictions

Hi,

We are a medium sized company with account managers managing accounts in several countries, but reporting to different country managers. So:

AM - Costa Rica           -> Central America Country Manager
      - El Salvador             -> Central America Country Manager
      - Panamá                 -> Central America Country Manager
      - Nicaragua               -> Central America Country Manager
      - Mexico                   -> Mexico Country Manager

Is there a way to set up security, so the AM can see all his opportunities, but the CM only sees the ones for their region?

Thanks!
Esteban
