Changing the object repository at a suite level

Hi, i’m wondering if it is possible to put your object repository in one folder then copy that folder. Then take your test cases duplicate them and put them in a new Test Suite. Then to go to your new suite and set your objects to reference to the new folder vs the old with out going through them one by one. I test a website that has one live site and several sandboxes that we test new features. We would like to keep the original tests working while we edit the objects in the new repository to be able to test the sand box. Any Ideas?

what about using GIT with branching feature?

We are going to just copy and past the project.
