Increase report retention period in Satellite 6.2

When looking at a host page in the UI (like https://mysatserver/hosts/myhost.domain.com)
In the upper left there is some text with a dropdown menu:
"Found X reports from the last Y days" Y is a value in the dropdown menu. This value is never more than 8, and the graphs never represent more than 7 days.
Is there a way to increase the period over which reports are kept?
Thanks,
Eric
