Using an "expected" time-series for forecasting

[gohar94]

Hi,

I am trying to specify a list of time-series that are my "normal" behavior and a list or an individual time-series which I want to check for anomalies against the "normal" list - is there a way to do this under the current release?
If not, is it preferable that I work on adding another TSMM model which takes in a list of .csv files as "normal" time-series and averages them at each time unit to calculate an "expected" time-series and then compares the other time-series with this?

Thanks.
