Get your camera positioned how you want it.  Open the camera manager and type in a name for your new camera setting.

THEN go to options> Set default scene and also make sure 'create empty scene at startup' is checked, the click the button to set default scene.

Close out of Vue.   When you reopen the programme your camera should be in the position where you saved it and you should also have that extra camera in your manager.

You can save more than one camera too.  Just make sure that they're saved before you use 'set default scene'
