Report on the contribution of a release towards the progress of a goal or initiative

Very often goals' and initiatives' progress will be calculated from the completion of features contributed to them, which will span multiple releases.

It would be great to be able to natively report on the contribution towards the progress of the goals and initiatives that each release has made.

For example, release 1 added 10%, release 2 added 8%, release 3 added 20%.
