using volume buttons as navigation

Hi, is there a possibility to define smartphone volume buttons as navigation buttons? It would be much simplier to use hardware buttons during presentation instead using the screen buttons.
Moreover, there would be no need to watch the smartphone screen and the presenter could focus entirely on the main screen.

Dear Jakub,

Currently you are not able to control it with your navigation buttons on the screen.

Thank you very much for letting us know your needs on this.
I am going to forward this to the product managers.

Warm regards,
