My team and I often need to attach files to our messages, e.g. an explanatory screenshot or a shipping label.  More often that I want to admit I mention the attachment but forget to actually attach it. 

Some email clients have a check-for-missing-attachments feature. A reminder appears when the Send button is clicked and detects a keyword such as "attached" or "attachment" in the message body, prompting the user to add an attachment if none is present.

Does Zoho Desk have such a feature, or is there an extension to add this?
