Hi Alex, thanks for your feedback. That is a good suggestion. Would you mind
adding a note to the scikits bug/feature tracker for this?
http://scipy.org/scipy/scikits/query?component=timeseries&order=status

Also, patches are welcome and would increase the chances of it getting into a
future release quickly.

Thanks,

- Matt
