Question about foobar copying and skipping of files Options

[wcs13]

Hi everybody, and sorry if this has been asked before.

Is there a way for foobar to skip a file during a batch copy operation if the file already exists in the destination directory ?

Long version below :
I have about 45.000 files in my music library, all of them stored in a secure & crypted NAS.
I need to keep in my laptop an ever-evolving playlist of about 1.500 files (FLAC and mp3). This weights about 20 GB.
Everytime I need to update the laptop contents, I have to erase everything in the laptop and copy the whole 1500 files again, which takes more than an hour (for crypting reasons), even if I have only added/changed a few files.
I'd love if the "copy" function of foobar could just skip a file if the file already exists, without stopping the whole operation.

Can this be achieved in some way, and how ?

Thanks in advance.
