Supplier Price by Quantity

We often have parts quoted at quantities of 1, 5 10 and 50. Right now I can not store that price data in DEAR. 

It would be nice to have something breaking out price by quantity in the Supplier section of the Product page. 

Then, for additional logic, a PO unit price can map to the lowest closest price. For example if we buy qty. 45 from Supplier B, the $368 unit price for qty. 10 would apply since there is no price for qty. 45 specified and the price for qty. 50 does not yet apply due to insufficient quantity.
