Hello,
it is not possible to switch from Effect to Effect with an Executor via Go and to master the Effect on the same Executor with a TempFader.
However, there is a workaround with another Executor as 'Effect Master'.
1) Select all fixtures to be mastered.
2) PresetType Thru At EffectForm 1
3) Store on an Fader Executor
4) Switch to Super Priority via Assign menu and change the Master to TempFader.
This TempFader can now master all effects running in the Programmer or Playback.
Of course you can create several masters for different attributes.
