Can we have different prices based on different uoM of sales?

Q1) Is it possible to have multiple uoM for Sales.

Eg. Inventory uoM = Each

Purchasing uoM=Box of 12.

Sales uoM = Box of 6 and Box of 12

So, is it possible to have two different uoM for sales? I know how to do it for one.

Q2) If price for each = 1 dollar, is it possible to have price for Box of 6 = 5.5 dollars and price for Box of 12 = 9.50?

Appreciate your suggestions. I am preparing for a demo for a prospect. So you could suggest for both 2007A and 8.8.

Thank a lot.
