Can you run multiple Instances of Oracle EPM Interactive Reporting on a server?

I'm using Hyperion Interactive Reporting but want to be able to have two separate environments on the same server (i.e. two different development instances with separate repositories and using different backend databases).

I've installed EPM on the server and created a user_project and that's all fine.   I want a second environment (same BQY's, different OCEs and data sources users etc) so that I can do two different sets of testing at the same time.

I've tried adding a second user_project but with the configuration tool this then appears to try to use the same repository and in previous releases we had separate ones.
