I need to be able to get a total opportunity value for a business and contact.

Some contacts have multiple deals being quoted and on the go, in either the same pipeline - or different ones. I need to be able to pull up that data in the dashboard (Or somewhere) to know the total value of work being quoted (total opportunity value) and over a period of time... for one particular business client or contact.

Please Upvote as this granularity in data is essential for good business in a CRM.
