Combine all parts in BOM

Like items in a BOM are combined by expanding the BOM, right clicking on the part and selecting Combine Identical Components.

When I have a complete assembly drawing, and create an indented non-numbered BOM, I want to combine all like items in the entire BOM so I can export to an Excel file and send off to purchasing to order the parts and materials.

All that RMB action gets tedious... Is there a way to "Combine All"?
