Calvin wants to see any applicant who accepted or was offered an opportunity within a certain date range. They find it too burdensome to have to first select the offered applicants, run the report, and then select all the accepted applicants and run that report. They would prefer if they had the ability to select multiple categories from the "Category" dropdown list on any given grid view. 

As an opportunity administrator, I want to be able to select multiple categories to sort by at the same time, so I don't have to create multiple reports.
