Can BTT map Kensington Expert Mouse buttons natively without Kensington Works?

I see where this has been asked in the past, I'm thinking of picking up a Kensington Expert Mouse Wireless Trackball, or a Slim Blade Pro.

I would rather use BTT to map the keys rather than have to install another Logi Options type software to go along with it.

Does anyone know if it's possible without the Kensington Works software?
