Build Player Content Duration

Currently it takes quite a while to build all your player content and most of the time it's spent compiling the scripts.

BuildScriptPackedMode.cs

Code (CSharp):

1.         static IList<IBuildTask> RuntimeDataBuildTasks(string builtinShaderBundleName)
2.         {
3.         .....
4.             // Player Scripts
5.             buildTasks.Add(new BuildPlayerScripts());
6.         .....
7.             return buildTasks;
8.         }

Is there anyway to some sort of caching or avoid this step in a way that doesn't break the build process?
