IntelliJ include a directory contained in an excluded directory?

Question

Can IntelliJ include a source directory contained in an excluded directory?

I am using Google Protocol Buffers and am placing the generated class files in the target/proto-generated directory. I have already excluded the target directory, is there a way to mark proto-generated as a source directory and leave the target directory excluded?

• target <excluded>
  • classes
  • proto-generated <include>
