[Feature Request] Choose destination of converted files

Description

Add an optional setting to be able to choose the destination of the converted files.

Use Case

Personally have my audio files under Z:\music\FLAC. When converting, it goes into Z:\music\FLAC\{artists}\MP3, however I would instead want them to go into Z:\music\MP3. Therefore for convenience purposes, making it possible to choose where the converted files would end up would be quite nice.

Additional Context

Setting would be optional under Tools > Audio Converter, before clicking "convert # files". Folder structure could either be directly copied from existing file structure or from the Naming Settings.
