[otrs] Add elements to Dashboard in 2.4.6

Hi, we're running 2.4.6 (update to 2.4.7 already scheduled) and I'm currently looking into how the Dashboard could be adapted to our needs. For now I have a simple question: Is it possible to add more Elements to the dashboard, let's say a second DashboardImage instance? I would have expected to be able to add these in the sysconfig, but found no way to do it in Framework -> Frontend::Agent::Dashboard. Did I overlook something? Yours Karsten
