We want to use Bentley Automation Service to automatically produce i-models that expire 7 days after export. Currently when we setup a job in BAS it only lets us set a fixed date for expiration instead of "today + 7 days". This means we have to update the job every week for the new date. Can i-model Transformer assign an expiration date to an i-model? And can it do it X days in the future rather than by a fixed date?
