Certificate per Environment in Environment Manager

In our infrastructure, it's common for us to have a different certificate for the DEV/QA environments than in the STAGE environment. Currently whenever we want to execute a test in a different environment we have to go into the Preferences and change the certificate. This can get tedious if we have multiple projects ongoing and some are in QA and some are in Stage as we have to change the cert over and over. It would be helpful if a certificate could be defined per environment, or perhaps the certificate in Preferences could be overridden if one was entered for the specific environment. Thanks, Mike
