OK, looks like STeffenR confused about mixers.
I +1 this feature suggestion.
You can set and test a pre-delay setting for any verb FX easily with the CQ:
-under FX tab, set you FX Level to LR OFF.
-under Processing/Reverb/Sends, set you FX to go to on AUX Out (OUT 1/2 in the example shown).
-under config/outputs, select you AUX Output Delay to you desire value
-link physically (with TRS cable) your Aux Out to any free input of the CQ (Input 7/8 in my example) and use this fader to set you level of FX send to L/R.
This will allow you to hear the FX with some pre delay.
Just for fun and testing.
