Hi Rich,
You can display this information on the Affected End User label. Here's an example of how we display the Location on the Requested By field.
<PDM_MACRO name=dtlLookupReadonly hdr="Reported By $args.log_agent.location.name User" attr=log_agent>
Here's how it looks..
Your affected end user field would look something like this.
<PDM_MACRO name=dtlLookup hdr="Affected End User - $args.customer.location.city $args.customer.location.state" attr=customer evt="onBlur='calculateUrgency()'">
