Proc Alert question

Is there a way to get yellow or red alerts for a given process based on number of instances.

For example, I'd like to get a yellow alert if there are more than 1000 database connections, and a red alert if there are more than 1500 database connections.

Right now, I have to specify two different proc check lines, and once the red condition is triggered, you get alerts for both yellow and red...

Is there a way to get a yellow/red condition via the PROC directive based on number of processes? Can't find anything in the docs that points this out.

Thanks, Taylor
