Bulk Price Quotes

As a seller, it's important to price my listing with the correct profit. A major player in the COG is shipping. At this time, ShipStation only provides the option to get a price quote for one weigh/size/destination at a time. What I have to do currently is, enter the furthest zone as a destination, enter a starting weight (and measurement). Find the best price for the kind of shipping service (usually the least expensive) and then change the weight (and measurement) to get the cost for another quantity or product. It would be much more convenient if I could have a spreadsheet or at least a list of the shipping quotes by tier's to get these quotes quicker and setup my selling price more accurately.
