I would like to make sub-layers within the audio layer. I want to assign a different color to each sub layer: 1. line level 2. mic level 3. speaker level

I have 16 mic level lines to pull to the audia flex.

What is the procedure of making a layer, changing its line width, color and then selecting to use that layer?

I have changed color over in the properties box, but I don't want to have to do that for each individual line. I am used to AV2007 and autocad, and neither of these are informing me on how to use layers in .s07
