Lot Value Calculator Individual Markup

Request: I would like to see a new field added to the Lot Value Calculator in the form of something like a "Markup" field. Have it work identical to the Default Condition setting, where each item added to the list automatically populates their condition as the Default Condition...but can also be modified at an individual level as needed. In this request, the Percentage Markup would act as the default value applied to each added item, but then each item could be customized as needed to have their own individual markup value.

Reasoning: I do a lot of trading and buying of lots, and find it difficult to use the Lot Value Calculator because of this lack of markup customization. I like to pay more for higher quality games, and pay next to nothing for low quality games or highly undesirable games. As it currently stands, I have to do multiple lot entries and printouts. I would love to be able to just add something like Pokemon Emerald at 80% market value to the same lot as NHL09 at 1% market value. This feature should be pretty easy to implement seeing as the structure for doing so already exists with the Condition field.

Thank you for considering this request!
