Can Marketpress be set to "Limit x" on sale items?

I have a client site using MarketPress that puts 2 items each week on sale, usually with a limit on how many people can buy at the sale price. Am I missing something where this limit can be set in the Marketpress dashboard?

It would need to be a limit per item, not a blanket limit for all sale items. This week one sale item has a limit of 2 and the other item has a limit of 4.
