Possible to enable "scan outgoing mail for spam" exim option PER ACCOUNT?

Hello, In the Exim Configuration area of WHM, there is this option: ------------------- Scan outgoing messages for spam and reject based on defined Apache SpamAssassin" score ------------------- Is it possible to enable this on a per account basis? We don't want to enable it for the entire server, because we have a lot of accounts and I think it would add a lot of additional resource usage load on the server. However, I feel this would be very nice to enable for a few trouble accounts that I suspect are sending spam. Thanks.
