Allow roll-up of feature scores to linked master feature

It would be helpful to allow a roll-up total of feature scores to a linked master feature. This is a requirement we have right now as we prepare to launch our custom scorecards on features.

Use Case:
- I have multiple features with scores that are related to one master feature.
- I want the master feature to include the total score of the multiple features.
- I know I can pull a pivot report with the information, but I want to see the information on the Master Feature record so that I can include the total in reports with other information about the master feature and related features.
