how to dedup row in a property set

Hi,

In my workflow, I have a query step that returns x records:

Asset Id      Account Id           Product Id

 12               123                      ABV

 13               123                      ABV

 17               123                      ABV

 19               123                      ABE

I want to dedup these rows by doing a group by (Account Id, Product Id)

the above property set would then look  like:

Account Id           Product Id

123                      ABV

123                      ABE

Is there a vanilla business service that can help here?

(If I'm not allowed to use scripting)

thanks,

Matt.
