Default Backup/Restore of Group Messages

Is there an app or method for backing up and restoring group messages correctly? I currently use MyBackup Pro for backing up data and apps. The issue I run into though, is with restoring sms messages - particularly group messages. It restores everything as individual sms threads based on the contact. It merges individual threads with group threads. Is there a way to avoid this? A way to have them restored exactly how they were when they were backed up?
