Go to Workspaces and Dashboards > Global iViews > Add New > Create a new Global iView from scratch > Type: Links List.
When adding the link, the whole link should not be pasted. The Relative link added should be starting default.aspx: Correct Link: default.aspx?requestUrl=..%2fFoundation%2fWorkspaceDashboard.aspx%3fworkspaceId%3d57%26dashboardId%3d48
Add the iView to the dashboard.
Go to the dashboard that has the relative link.
Now when users click on the link they will be redirected to the correct dashboard instead of the Home Page.
