How to show another end date in Project Center View?

Hello community,

in our Company we want to Show another end date in the MS Project Server Project Center view as the Default one.

Instead of the end of the Project we want to Show the product availibility date.
The product availibility date is a Milestone in our Project plan and differs from the end date of the project.

Is there a possibility to show the product availibility date?
In the MS Project Server Settings I just find the default end value to to show in the Project Center view.                                    

Thanks in advance!
