So I have a directory structure that contains all of my music as FLACs, and I want to periodically add a few albums, then convert them to m4a and mp3. When I add the FLACs, and convert to, it gives me an option for each file to overwrite, overwrite all, skip, or cancel. I'd like to skip all that already exist, and not have to skip them individually. Is there any plan for that sort of feature, or some other way to do this?

I've been playing around with dbPowerAmp for this, but it seems flaky in a number of areas, and I'd really rather just use fb2k instead.
