Populating Future Data - Updating Multiple Values on Single Tag

We have just  begun looking into Future Data with PI and I am running into an issue.  I would like to create a single tag which contains 168 hours of forecast data.  This forecast data is updated every hour therefore I would like to overwrite the previously written 167 hours of forecast with the new data.


In PSE is it possible to:

  • Write multiple forecast values to a single pi tag (each offset by an hour)?
  • Align the output timestamps such that the previous forecast for a given hour is overwritten?
  • Do all of this without creating 168 analyses?


For simplicity, assume I have 168 separate tags representing each hours' forecast.


Thanks in advance,
