DCA Spill, (QU-5, QU-5D, QU-6, etc...)

Does the QU5,6,7 have DCA Spill function?

Since the structure of these consoles has become very similar to the SQ series, but unlike those, no DCA spill is shown in the manual and the app (Soft Key), I would assume that it doesn’t currently have one (yet).

You can press the PAFL button on the DCA strip.
Now all members of this DCA will flash their PAFL led.
Not exactly what you are looking for, but it can help.

Just press DCA select button and the screen instantly shows all inputs assigned.

DCA Spill is, unfortunately (or thankfully), something completely different (see also Google).
When this function is used, all channels contained in a DCA group are immediately made available to the user as faders.
This means you can, for example, instantly access and adjust faders of a drum mix, even if none of these faders are currently in your fader bank.
