Hide columns selectively in Pivot Table report

The Pivot Table reports are beautiful! But I need help figuring out how to filter columns selectively from the user interface. We are showing depreciation by month, and I need to add future months, so the number of columns will continue to grow. Months are columns (each month is a field in the data table), so I can’t filter by row values. Is there a way to allow a user to hide selected columns?
