Jump to new Keynote File at the end of Presentation

Apologies if this topic has been discussed, in the 11th hour for a solve. Is it possible to trigger a new keynote file at the end of my first Keynote file?

I know this can be triggered via "enable link" in the inspector on an object. I am wanting to run Keynote presentation "A" with an apple remote, then the last slide of Keynote A triggers new Keynote File "B".

possible? yes, I know I could just tail them together in one keynote file but that is not what I need to do. I need presenter B to be able to work independently until the last minute before the show and I just want to link to their file.

Thanks in advance for any solved or helpful answers.
