VOTE: Add multiple tax category integration for QuickBooks (PST/GST support)

Add tax another tax category integration for quick books so it understands when you are entering more than one tax. For example, in BC we charge PST/GST on things that we do not install. When I select this option I can have it choose that option in quickbooks.
