Handling a compressed and uncompressed library simultaneously?

[pgbj]

hi
first off, thanks again for a great piece of software which along with Bubble has revitalised ny music listening.

I have all my library in FLAC in one folder hierarchy and a mp4 compressed copy mirror. When I am using my lical Cambridge CXN renderer I use flacc. But sometimes I use a renderer that only supports mp4. Is there a way of running another instance against this other hierarchy?

(I am running minimserver on a Synology NAS)

thanks
