Adding a checkbox to an Access 2007 report

I've created a report that will be constantly updated with new records thatmy group is generating for another group within my company. The report will be a checklist for tasks to complete. Is there a way for the report to have a checkbox so that the users can indicate which tasks they've completed, and which ones are still to be completed? Otherwise the report is just going to get bigger and bigger and will get confusing.

Any help would be greatly appreciated.
