Excel Services 2010: Set odc with relative path to avoid having to change it for every environment

Hi All,

we are using Excel Services in SharePoint 2010. We have several reports that use a connection file on the SharePoint to establish the connection to SSAS.

Our problem is that we have to specify the full URL of the connection in the report:

We could live with that for our Test environments. But in production, we will not be able to manually update the link. Is there a way of specifying this in a generic way so it would remain static across environments? Or as second best solution, do you know a way of programmatically updating the url (eg Powershell)? Or any alternatives???

Many thanks for your help!
