Adding price to an attribute in dropdown

[Jinfaa 0]

Is it possible to add a price to the drop down menu for attributes?

 

For example:

7kg - $1.50

14kg - $3.50

I do this all the time on the Combinations tab of the item, stock feature of PS. I haven't figured out how to make a nice report, though, that shows wholesale cost, sale price, and sales history of each combination (for tax time).
