The FindRelatedProducts action updates the property used in the Upgrade table
with the product codes
of the products it finds. You could try adding your Product code to the same
property, although I
don't know what happens if the product doesn't exist. You might need to use a
custom action to
check that. If the property is blank after FindRelatedProducts you'll need to
set it to "{GUID}".
If it's not blank you'll need to append ";{GUID}" to it. But like I said, this
will need some
careful testing.
