the stats from formula

[dmicu]

Hello,
In CCPulse, is it possible to define a formula with stats from different objects?

For instance I have an interaction queue IQ1 where I have 10 emails entered and a second interaction queue IQ2 with 5 emails entered.
My intention is to create a stat that = IQ1.Entered-IQ2.Entered.

I see that I can create formulas from stats on the same object [the agent JohnDanes or the group MilanoAgents];
But is it possible to take stats from multiple objects?

Thanks,
Diana
