Currently, when you use "Copy to..", it can copy other files in the same folder but there is no filter support.
I wish it could be like the converter, where you can choose what files to copy.
A use case:
I often copy (if it's lossy) or convert (if it's lossless) some audio files from my main media library to my mobile devices for playing.
I want to copy external covers together with tracks.
It works flawlessly for converter + filter "cover.jpg; cover.png".
It doesn't work well for "copy to" because it has no filter, and it will just copy the whole albums, instead of just the tracks I select.
I fully support this suggestion, it would be very helpful.
