SSRS custom subtotal

Hi,

I have a report in SSRS with a subtotal that is totaling everything above it, but I need to subtotal only one item.  Below is a simple example of what I am trying to do.  I still want to see the details and I want one subtotal, in this case just the Orange.  I have tried creating a Dataset with the value I am looking for and using it with the InScope Function but it keeps totaling everything.  Any help would be greatly appreciated.

Currently

Product Name, Cost

Orange              $1 

Apple                  $2 

Grapes               $4 

Orange               $1 

Apple                   $2 

Orange                $1

Subtotal              $11 

Goal:

Product Name, Cost

Orange              $1 

Apple                  $2 

Grapes               $4 

Orange               $1

Orange                  $1
