Roll up documents & proofs from tasks/projects into program level

Currently documents/proofs roll-up from the task level into the project level which is great.  But we also need documents AND proofs to roll-up to the program level (in our case, campaign).  Many on our team need to see all documents across multiple projects in a project/campaign.

This would also help with users trying to find certain documents related to a campaign but unsure which project it would be in.
