[effect engine] how to control only the speed ?

hello
here is a basic question
i would like to record 2 cues in 2 different cuelists
- one cue contains a move p/t effect ( effect 1) and controls the size of the effect only with ifcb
- the second cue controls the speed of the same effect or any effect using also ifcb
like this i can control with the 2 faders the speed and the size of the effect
is it possible ?
how to record only the speed of the effect or the size ?
do you have tips to play with effects and cues ?
