External URL for SM 9.52 Dashboards?

Hi,

our users really like the dashboards. Now they are very interested wheather or not it is possible to access a dashboard directly by an URL, like the direct access of an Incident or Request. I already tried 

http://<host>/webtier/dashboard.do?id=nnnnn

but this was not successful. With this only an empty page comes up.

Any ideas?

We use SM 9.52.

Best Regards

Volker
