How can i alert on Total Interface Traffic without a custom SQL?

Basically trying to monitor the downloaded and uploaded data on a specific interface on a specific node.

I can do this with a custom SQL, and have written the SQL, however when i do that it runs against all nodes and generates too many alerts. (SQL Below)

SELECT Total FROM

(

SELECT CAST(SUM(InterfaceTraffic.In_TotalBytes + InterfaceTraffic.Out_TotalBytes) /1024 /1024 /1024 AS NUMERIC(3,2)) as 'Total'

FROM

(Nodes INNER JOIN Interfaces ON (Nodes.NodeID = Interfaces.NodeID)) 

INNER JOIN InterfaceTraffic ON (Interfaces.InterfaceID = InterfaceTraffic.InterfaceID

AND InterfaceTraffic.NodeID = Nodes.NodeID) WHERE (  DateTime BETWEEN '27-Nov-2014 00:00:00' AND '27-Nov-2014 23:59:59' )

AND ((Nodes.IP_Address = 'X.X.X.X') )

AND (Interfaces.InterfaceID='XXX')

) a

WHERE a.Total > 1

I cant find an option with a standard alert being built to show InterfaceTraffic.In_TotalBytes or Out_TotalBytes

My knowledge of Solarwinds is Beginner and im learning how to build the alerts smarter.

Is there anyway to do what i want without CustomSQL?

Or is there a way / something i am missing to make my CustomSQL only apply to the node i want once the alert is created?

Thanks
