Windows Phone 8 Project Debugging

Hey, I was looking for this around the internet, but still cant even know if its possible so I want to know if there is a way to still edit Unity classes I created within my game in Visual Studio 2013, build them and therefore make changes to my application from VS so I dont have to build whole project even if i make small changes like declaring variable from Unity all the time when I want to run it on my WP Device such as Remote on Android or iOS??
