Ah - sorry - I was thinking back to a problem a couple of weeks ago that i'm readdressing - remembered properly now - I can bundle them like that, but let's say I wanted to feed that bundle wire into a subVI - is that possible?
If so, what 'control' or 'indicator' do I need to drop onto the subVI front panel / block diagram to wire to on the connector pane?
The easiest way you can do that is right click on the wire between the bundle/unbundle and choose create control. Place the control that comming out of this in your subvi and then you can connect them.
I would start by getting all my ques into a bundle, then I would right click on the bundle and create an indicator this will have all the ques references in it.Then I would copy it into the subvi and make a control for it. Here is an example I threw together.
