Only show text before email trail
CSM/CAM Version : CSM 9.31

Is it possible to trim the email trail out of replies from the Customer so that when it updates the ticket it only shows the text that they sent, not the text from the email from us. I've tried adding a modifier to the 'Body' in the Mail Monitor to only use text for the start to Before 'From:' (if that makes sense!?) but it fails.
