Shipping Discount For each Prodcut

Hi,
Is it possible to set pick up discount for individual Products. For instance let’s assume my pizza price is $18.00 and Icecream price is $8 now I want to give shipping (Local Pickup) discount of $2.00 for Pizza and $1.00 in Ice Cream. So If customer selects local pickup then they should get those discount. What I’m trying to do is I should be able to provide shipping discount for individual products but not for whole category. Each products should have different shipping discount. Thanks..
