E+ does support primary / secondary, but does not support a variable speed pump on the primary side (use constant speed)

Subject: [EnergyPlus_Support] How to model Primary and secondary both variable pumps in Chiller water systems
Hi, all group, i need some help!
I got this warning when i try to simulate a Primary and secondary both variable pumps in Chiller water systems (The chiller incorporate VFD):
** Warning ** SetupCommonPipes: detected variable speed pump on supply inlet of TwoWayCommonPipe plant loop
** ~~~ ** Occurs on plant loop name = CHW LOOP
** ~~~ ** The common pipe model does not support varying the flow rate on the primary/supply side
** ~~~ ** The primary/supply side will operate as if constant speed, and the simulation continues.
It seems that Commonpipesimulation in Plant Loop doesn't simulate primary and secondary variable pumps.
There is any way to could model primary and secondary variable pumps??
Thank you,
Dante Garcia
