How to set a comparison date at entire report level

[Aventuri]

Hello, I need the date comparison to be applied for the entire report, not for just one widget, how can I get that?
Thank you!

You need to define for each element the Data Range Dimension. If you want to apply the same for all pages, ist necesary to change in your date range control at the report-level.  (secondary button over data range control / Make report-level).

OK but what about the comparison? In the date range control at the report-level I can only set the date range of the report, there's no comparison setting...
