Subject Re: Output file prefix

Hey David,

There isn't a way to muck w/the file output prefix on a per-collection
basis. Would something like a PathPerKeyTarget work for this situation,
where you would have four keys for the different output directories and
could sort of union together the PTable<String, Whatever> instances that
you needed to create on a particular run?
