AutoCAD Civil 3D :: Layer Filter For Different View Port Colors

In my template, is there a way to setup a layer filter or layer state to automatically plot a different viewport color when a new drawing is created and viewports are made?  Note, my template does not have viewports premade. 

I've set all my Existing and Proposed Utilities to use the WV Miss Utility colors, but I designated either pale (odd color#) for existing and bold (even color#) for proposed so that in model space there's a visual difference.  See a few examples below:

V-SSWR-PIPE (color 91)
V-WATR-PIPE (color 151)
C-SSWR-PIPE (color 92)
C-WATR-PIPE (color 152)

Our Civil dept doesn't use colors, but our Utility dept does occasionally especially when Aerials are used.

When we create layouts/viewports in a drawing, it would be nice to have viewport layer colors automatically be set to plot black or gray or be on/off depending on existing conditions sheet or proposed site plan sheet.  The only way I know of is if I would set up viewports inside my template with VP Color Overrides preset and/or VP freezes for certain layers, which I'm hesitant in doing.
