In Dashboard Maintenance you can select multiple dashboards from the DashboardID search. They will all load in the tree on the left and you can then go to Actions > Deploy All UI Applications.
Great, thank you. I didn’t realize Dashboard and Dashboard Maintenance were separate screens. That worked for me.
In case anyone else finds this thread; Dashboard Maintenance is located in the traditional menu here: System Management > Upgrade/Mass Regeneration > Dashboard Maintenance
