I'm not enturely sure of the feasilbility of such a request, but it would be fantastic if we were able to edit metrics in multiple reports the same way that we can edit date & granularity, and reporting suites. I manage a large number of dashboards and with our recent migration to SC 15 there are specific metrics that have ceased to be useful while others have surfaced as usable. Being able to edit dashboards in this fashion would be exceedingly helpful.
