Hello,

I'm using the pipeline.yml to run multiple configurations at the same time. Basically each and every config file are performing a soap call (where the date is today), filter the data and upsert the data in ES. However, we now want to get the data for the past 20 days (including deltas), which means that we need to perform the soap call with now - 1d, now - 2d, now -3d etc. Is there a nice and clean way to do this? I was thinking of sending along a parameter (or property) in the pipeline where I just perform the pipeline 20 times with a parameter now - xdays.

Thanks.
