Am I crazy or is bronze plate not stacking?

I had a look and there's graphics and an entry for it, but in game it doesn't actually stack, nor is the icon for stacking in the first tier.

Would you consider adding a signal input to disable a stop?
I currently have to add another logistics object just to get the Enable/Disable to appear.

I figured since I'm already hooked up to a constant combinator via lamp it might be possible to disable it via that.
Or even if it wasn't actually ...
