Calculated metrics created in Discover available in Site Catalyst

I can create awesome calculated metrics in Discover.  Specifically using segments to calculate a metric - this is amazing and powerful!  But my awesome dashboard capabilities in SiteCatalyst are also a fantastic way to share and communicate how these metrics are performing.  If only we could bring the two together.  Meaning, when I create a calculated metric (say using a segment to calculate it) have that metric then carry over and be available in all things SiteCatalyst - specifically the funnel reports in my dashboards.
