Having troube with code to swap line pattern

[ThirdDimension]

Here is a brief summary of my situation to set the stage for my question.

I create wiring diagrams for the installation of wires.  I created 4 custom line patterns to represent the 4 wire types.  Single conductior or multi-conductor wires are shown with solid parellel lines. 

On my dwg's, I also need to show some existing wiring, in which these four wire types are depicted wtih parelle dashed line, so I created 4 more custom line patterns with dashed lines.

I was able to create a right click selection option to toggle between the 4 options.  This works well as if you want to change the wire type, all you have to do is right click and select the option.

My question is how to add a right click option "EXISTING?" that will toggle the line from dashed to solid, but retain the seleciton of wire type?

Thanks!

Not really clear where your problem is.
Check the attachment, it shows an example of options that can be checked in individual categories.
