Retain multiple versions of active report on iPad

[DaveLevick]

I have an Active Report created using Report Studio 10.2.1 that will be run once per month and delivered to iPads via email.
I want to retain each months report on the iPad, but each new report I send overwrites the last one.
I've tried changing the name of the report by including the date in the title, but it still replaces the existing report.

Is there anyway to achieve this?

Thanks
