Change Directory for "Export to " (Music Export)

Feature description:

This feature would allow the user to select which directory they would like to export their media to.

Problem solved:

This solves the problem of using a DAP with a small internal storage, but a large micro SD card.

Being able to select where the music is exported to would allow me to bypass this hardware restriction.

Brought benefits:

This feature would allow me to export all of my music that I downloaded onto the SD instead of running into errors for insufficient storage.

Other application solutions:

 
Other apps allow changing the entire readable directory for app caching and offline storage. I understand this is not within the scope or desire of Symfonium
 

Additional description and context:

 
For clarities sake, I have included a screenshot showing the setting I’m referring to.
