Dynamic offset in link to filter
Is it possible to use a dynamic offset? I currently have a subquery that is linked to the date filter of my master query. The date filter in the master query is there to select a start date and end date. I want my subquery to show data of the same period as master query but just the same period before that. So let's say I select a month in master query. Subquery should show me the data of the month before. If I select one week subquery shows week before, etcetera.
Thanks in advance!
