The retouch module (3.4.4.12) might be helpful, especially the wavelet decompose part of that module.
Bruce Williams made a nice video about this module (the wavelet part starts at around 10:30):
Basically you work with layers (scales) that go from very fine to course and you can more easily identify the problem spots. It isn’t a magic wand so you do need to put the effort in, but I really like the fine-grained functionality.
