I'm using FS in a multi-tenant scenario where I'm trying to set hold music via the hold_music channel var with a file_string:// of hold music files.

However, I'd like to get something closer to local_stream:// behavior (without being able to use it since hold music is dynamic). Ideally, I want callers to hear a random file from the hold_music file string each time they're placed on hold. Is there a file handler like file_string:// that would pick a file to play randomly? Or another suggestion to accomplish a similar goal of getting callers to hear something different when they're placed on hold multiple times?

Best,

Colin
