I'm creating an Hours report and using the following Text Mode to currently show all teams a user is assigned to.
displayname=All Teams
linkedname=owner
namekey=view.relatedcolumn
namekeyargkey.0=owner
namekeyargkey.1=owner:teamsListString
textmode=true
tile.name=component.teamsList
valuefield=owner:teamsListString
valueformat=HTML
viewalias=owner:team
This provides a comma delimited list like Team A, Team B, etc. I've tried using listdelimiter, but it didn't have any affect.
