Metric studio to Report Studio?

[Jeka]

Hello Guys,
If you create KPI's formulas in Metric Studio (without using Metric Designer) can you use the same formulas that you wrote in Metric Studio in Report Studio without re-writing them?

If yes, would this effect performance, and how would you do this?

Thank-you!

MODIFY -----------Say if i create a package in FM with the formulas i need and posted to the C8 server than i can  use that package in report Studio.
What about if i create package (scorecards) in Metric Studio using simple formulas to track goals (KPIs) and some users want to see those KPIs is report Studio(create a report using the same exact formulas) is it possible to use that package  from  Metric Studio so not to waste time to re-write those formulas in report Studio?

i was thinking if you can then that might be a performance issue because Metric Studio is not the tool like FM, but that just a thought!

thank-you!
