Import Teams, Roles and all Users into Sandbox

i ust want to add.. an sandbox supposed to be an exact copy of the production environnment, if we do change it’s not an exact anymore so our test a less accurate. and try to make it identical it’s time consumming and if test fail et we have to recreate de sans box again we have to redo it again.

what we need is an exact copy of the prod environment as a sandbox.

Thanks
