Summing Meter Accumulators (from DNP) in RTU

I've recently moved jobs and am trying to come up to speed on SCADA and metering. Through an unfortunate series of events, it has happened that we are in a situation where we need to sum two meter accumulators (read via DNP/Serial) in our D20 RTU, once we've polled them. Unfortunately, I cannot see any way to access the accumulators from within the Calculator Module on the D20. Does anyone know if this is possible? Or, is it possible with another device such as an SEL RTAC? This seems like it should be so easy, yet I've heard several coworkers state that accumulators can't be added. I just can't understand why this would be the case.

Any ideas?
