Hi,

There is no report called "Upcoming tasks". There is a "tasks starting soon report" that uses the Date Range filter. It sounds like this may be a custom report? It's difficult to suggest how to edit the report - without knowing how it is made - but generally, yes you can copy a report and edit the copy.

To copy and existing report:
Project tab,
Reports
Find the report and single click to select.
Click the Edit button and give the report a new name.
Assuming the report is running a filter, you should see the name of the filter appear on the definition page.

You may need to modify the filter to include different date ranges.

So - to help further - I'd need more information about the filter definition.

Find the filter and look at the definition (View tab, filter drop down, more filters, edit) and post back with the details.
