Klinzey, thank you for your reply.
I do agree with your point of view about barndoors, but with scrollers I do disagree. My scrollers always have the same Ch number as the fixture they are attached to. So par can Ch 1 will have a scoller attaced to it and that has Ch 1 as well, the same way the this would be patched in any LX desk ( think multi-part patch fixture). And yes I can add the Ch number in Lw, but that seems rather backwards. IMHO a "intelligent" accessory like a scroller should by default take the Ch of the parent lighting device.
