Fleet Accounts: Set Default Vehicle

I traded in my first Tesla and bought a new one.  I decided to create a new teslafi account for the new vehicle and link the two to create a fleet.  My first tesla is the master and my new one is the linked account.  When I go into either account my original vehicle is usually displayed as the default so I need to go into the vehicle menu and select my new vehicle.  Is there a way to set my new vehicle, in the linked account, as the default so I don't need to select it each time I login?

Cheers!
