I've done to link the dashboards I want (saved dashboards) it if with a custom link on the DMI:
(change for https if https is eanble on DT)
And As argument:
argument=online://[Source o DT SERVER]/[Dashboard Name]
I hope it helps.
forgot to tell you, you can create as many links as application are and as many dashboards on DT as applications are. Then in your DMI you create as many links as applications and with a contion to show the link based on the application name(Application == "your application") and on the link you put the DT dashboard name that macth with the application
