You could maybe try being fancy and using $$([]) notation with something 
like NumJobStarts (or some other attribute on the job that increments). 
You wouldn't get a single output file but a numbered set of them that 
you could concatenate together.

Something along the lines of...

universe = vanilla
executable = /bin/date
output = out.$$([NumJobStarts])
on_exit_remove = false
should_transfer_files = always
when_to_transfer_output = on_exit_or_evict
log = append.log
queue 1

You could also try using stream_output[1].

Best,
