Multiple AOS Instances to single SSRS Server - AX 2012

How do you (if possible) point more than one AOS to a single Report Server?

I tried creating a new Report Server configuration in AX 2012 pointing to the same SSRS server with a different AOS selected, but when I launch the client I get the error:

The default Report Server Configuration ID could not be found in the SRSServers table.

I also tried setting the new one to Default, but the same happens on the original AOS.  Ideas?

Thanks
