Effect Morph

As the manual states there is a possibility to have an effect morph from one cue to another rather than the first fading out and the other fading in.
(Ex:
Cue1: Step-effect on X deskchannels in 80 bpm.
Cue2: Step-effect on X deskchannels in 100 bpm.
Wanted scenario: Cue1 effect gradually speeds up to the effect in Cue2
UNwanted scenario: Cue1 effect gradually fades out without changing the tempo at the same time as the effect of cue2 fades in at new tempo, making the cue fade totally berserk.)

How is the wanted scenario accomplished?
