IW22 user exit, enhancement or other construct after work order save

My users are using GOS & BDS from within IW22 to attach documents to a notification and then creating the work order for the notification. They want all the links to documents/URLs for the notification to be copied to the WO. I have been able to do this for other IWxx transactions but the only user exit I have been able to access in IW22 is prior to the save of the work order. Looking for any possible solutions to this issue.
