Update project status based on the last finished milestone tasks in a project.

Very often, PM has to edit the project status based on the last finished milestone task. 

We would like the system to update the project status automatically.

Taking the following project template as an example

This project has multiple phrase such, Project Definition,  Design-R0, Fab-R0 etc. 

Under each phrase, there are some milestone tasks (e.g, NPOR-Initialization, NPOR-Feasibility study) highlighted with red.   

We create the corresponding project status in PI, so that when the milestone is completed. PM can update on the project status to the corresponding milestone. 

It would be great that the system can smart enough to update project status based on the last completed milestone task.
