disable the row limit of a sharepoint list data source

 I have a report that uses a SharePoint list data source. Occasionally, the list will have more than 2000 items, but the report only displays a max of 2000. Using fiddler, I can see that the call to SharePoint has a rowlimit set to 2000.

Can the rowlimit be disabled or increased?

SSRS 2008r2

SharePoint list data source, connecting to a SharePoint 2007 list.

Thanks,
