Capture Folder a little inflexible

Hey there! This is not a bug, but rather a feature request. At the moment, one can either capture everything to a singular folder, or to the cachefiles sub-directory of the project folder.

As I use Kdenlive to do audio capture, I do want the audio files to be with the project, but it is a little bit of a pain to keep on looking for the captured audio files in between all the other files in that directory.

I would love to have the option to choose: %PROJECT FOLDER%/Captured Audio as an option so that the audio are kept separate. I suppose the same could be done for Screen grabs as well: %PROJECT FOLDER%/Captured Screen

For exported frames and video segments they might have the option to start in their own respective folders, but I do like the option that I can specify custom directories on save.
