Feature request - thresholds for CPU utilisation (not load average)

I see that Buchan asked for this a few years back. Has anyone done this. I would like to start alerting on %CPU not LOAD. I would still like to graph LOAD and have that show up under trends. The % CPU is already in Trends being graphed it would be nice just to pull that over to the CPU column.

Here is the first request:
