selective denoising

Apologies for a couple of noob questions:

1. I've been trying to find a way to apply a denoise filter to only the U-channel in YUV, (or R-channel in RGB) leaving the other 2 channels alone. Please can anyone suggest a filter or method for achieving this ? So far I've only come across Luma/Chroma filters - I need to get inside the Chroma ...

2. I was also admiring the hue-selector in Tweak ... I wondered if there is something similar for RGB/YUV levels somewhere ?

Any pointers much appreciated.
