At the moment we don't support variable time windows, so you need to set the time explicitly and not load it from the reference data. Sorry for the inconvenience.

A workaround, in the case you have only few different time durations, would be to have different steps/subqueries for the different times and use a where clause to create or not an output for that step.

Let me know if you have further question.
