Invoice importing and inventory update

Hello, I´m having the following issue: when importing the marketplace sales, using the invoice importing excel sheet, it works fine ...but...(allways a but)... the sold items are not updatet in the inventory, unti I open any imported transaction in "edit mode" und save it again without changes to get the items discounted from the default warehouse. I miss a sheet in the import excel that specifies SKU and warehouse for each sold item ... any ideas? or sugestions? Thanks for a good answer! Best regards!
