Ability to Choose Multiple/Different Contacts Within The Same Organisation

Please add the feature/ability to be able to select different contact names (like a drop down menu) from the same company so as to be able to send, say a quote or invoice, to the appropriate contact or department within the same organisation. We deal with a variety of contacts within the same organisation depending on the project and each project is overseen by different people and the quotes/invoices are approved by these managers before they are processed by their accounts.

Different names and different email address and one or more at a time.
