How to add a patch as attachments to the notifications sent by Crucible?

Hello,

Is there a way to make Crucible to include the full patch (pre-commit, SVN) in the email notification when a review is created?

I checked Customizing email notifications | Crucible Server 4.8 | Atlassian Documentation but it appears these templates do not support embedding full diffs into notifications.

I posted the question on AtlassianCommunity but no answer so far, so wanted to give it a try on the DeveloperCommunity.

Thanks,
Haitao
