TouchOSC and Framing Shutters

How do I set up a control of the framing shutters in TouchOSC? While for other wheels, like pan, it is simply /eos/wheel/pan, but...





don't work.

And it seems, for fixtures with barndoors, those are even different controls (barndoor 1/3/4, wheel 12-15). The numbers 20 to 27 are visible in the diagnostics tab when I modify the frame wheels on the console...

The show control guide isn't helping in that way really. (Though I did modify the EOS_TouchOSC template in other regards successfully so far )
