Is there a way to embed a custom listview into a dashboard?
It isn't possible to embed any portlet into the Dashboard Designer, though you could use a table object but it lacks the flexibility (really, it's ease of use) that you'd get out of a List Views and can be difficult to implement.
You could get creative and setup a view within the Dashboard Designer and add that as a standalone portlet in a page and then next to it/near it could add a List View? I've done this before (reference below) and it's works out well.
This page uses a classic dashboard portlet for the alarms and logo (top) and then below it are a number of List View and Performance Report portlets.
