Not that I'm aware of...all companies that carry the paint colors sell them individually. I think because they're so specialized in subject matter, that it wouldn't justify the costs to bundle them together like you'd find with aircraft...OD with Neutral Gray, RLM 74 with RLM 75, etc...
If you want enamels, then White Ensign Colorcoats are the way to go. Testor's Acryl and PollyScale both do these colors in acrylics. Tamiya doesn't do these individual colors, they provide mixes in their instructions usually.
