Ability to generate invoice/revenue by project type or project unit

Summary:

Hi,

Do we have functionality to generate invoice/revenue by Project Type or Project Unit. We have multiple lines of business in a business unit. The lines of business are defined as project unit and have their specific project types. Each line of business would like to generate their own invoice. However these values are not available as parameters in the generate invoice or generate revenue process. How can we achieve this requirement? Do we need to have contract types similar to our Project Types?
