Supplier Catalogue Extract/Import

It would be really beneficial if a supplier catalogue extract could be exported that details all the fields as per the Products extract, but filtering it down to just the products relating to the pre-specified supplier. You may ask why not just filter on the specific supplier in the Products tab, well where there are products that have multiple suppliers the fields relating to the supplier data show each respective supplier details within one field with a pipe separator which is a nightmare to work with and often results in manual entry to update the data. The fields affected are as follows: Suppliers, Supplier SKUs, Supplier Currencies (Read Only), Supplier Costs, Supplier Stock Levels, Supplier Lead Times (Days), Supplier Carton Qty, Supplier Carton Barcode, Supplier Unit Of Measurement, Supplier Minimum Unit Order Quantity, Supplier Purchase Order Item Delivery Cost, Supplier Drop Shipment Item Delivery Cost, Suppliers Reference.
