Legend improvement ideas for event based trend graphs

The new Advanced Event support in TrendGraph control is a great add and I'm just getting started using it. But there might be some things that could be done to improve the legend. In the example below, I have 3 orders that ran on the machine and I show 2 tags for each. While the existing legend options have value, in my case I was thinking more like showing the 2 tag names and the color for those bands and showing the 3 production orders and the color for those lines. With some help from Steve, this is as close as I got but it also required manually adding some labels and using the grid display type for the legend with a max grid rows visible. 

I started with this:

 and really wanted something more like this:

The tag labels could also be something like this but I went with side labels so as not to potentially have my labels over data.
