TFS 2013 scrum report upload Project Collection folder instead of Project folder

Hi

  we are using TFS 2013 with Scrum Process Template. We have project collections called "MyProjCollections" and under project collections I have five project which are "Project1","Project2","Project3","Project4" and "Project5".

I am configuring TFS 2013 server as per http://msdn.microsoft.com/en-us/library/dn130125.aspx. As per instruction

I have uploaded scrum report to "Project1" by using following command

tfpt addprojectreports /collection:http://MyServer:8080/tfs/MyProjCollections /teamproject:Project1 /processtemplate:"TemplateName"

My question is that do I have to uploaded scrum related reports to all the projects individually (in this case five times).

Is that possible to update reports on collection level instead of project level?

thanks

Drew
