Windows 10 Dell Desktop w/Bluetooth question

I have a Dell 660 Desktop computer running Windows 10. It has built-in bluetooth. I would like to purchase a pair of Sony Bluetooth headphones for use on my treadmill and listen to the Pandora Add-on.

Once my bluetooth headphones are paired, will they appear in the Kodi Audio Output Device list ?
Is there a way to configure Kodi to make just the Pandora Addon use bluetooth ?
Will I need to make any audio setting changes to my computer ? (besides pairing)

Kodi 17.1
