Is there a way to use FePEST to calibrate transient parameters?  I am trying to calibrate a transient model by adjusting monthly recharge values. 

In my model, I specify in/outflow (recharge) via an expression that multiplies the recharge rate (from the steady-state calibration) by a recharge factor (time-series POW).  For example, in a month when the recharge is double that of the steady-state; the corresponding recharge factor in the time-series is 2.

Can FePEST be used to estimate the values in the recharge factor time-series?  If it cannot be done via the GUI, can it be done from the command line?
