Hi ,
What you want done is certainly possible , but a lot of work.
The dashboard is the final output , and is dependent on calculations which are present on a separate tab ; if you want the dashboard boxes to be incorporated in a different workbook ( KPI Simple Dashboard ) , then you might have to bring in the Calculations tab also ; since the calculations depend on various configuration settings which are defined in the Settings tab , that too might have to be brought in.
All in all , it is going to take a lot of work , but it can be done.
