Boot runner profile how to setup bootable USB-stick at bootscreen

Dear Support team,

Can I have your guidance how to setup in the profile manager of my Bootrunner 3 a bootable USB-stick at the startup of my bootscreen?

Is there also a way to simulate the ALT/OPTION-key to choose out of the Bootable devices at the Bootrunner bootscreen?

Thanks!

Sure. Just set up the external device as a custom setup:
