Having gone through it, I may be missing something, It would be useful to have the ability to set multiple rules for products themselves. At the moment you can set a rule for individual customers that they purchase specific Products with a rule against them and upload the specific price to Supplier Price Lists.

However I have 40,000 products on my system of which 10% of those are from 1 supplier, where we get a set cost price every year and we have to manually adjust the prices on those 4,000 products to the new Sell price. It would help to put a blanket rule to multiple products at once for a sell price against the new buy price whenever that is adjusted and equally if there is only a sell price provided from a supplier, the ability to put that price in with a rule against the supplier to automatically get the set discount. 

Without multiple spreadsheets and having to reupload every year and remember to Excel coding to adjust, I think this would be benefitial
