"Member Organizations" module - for projects?


I am looking for a way to have a function similar (identical almost) of the “Member Organization” feature fro Accounts, but used for Projects.

Basically the idea is that I have, for example, 10 projects that are related to the same contract. Th eprojects are all individual, but the contract is a single contract.

I want to be able to link the 10 projects together so that when someone looks up one project, they wil see “Master Project”, that I can click on in the project area, and will then list the 10 projects isted under teh mastr project heading.

It is the same exact concept that is used to regroup member organizations. But, applied to projects.
