Momentary buttons attached to Esplora's tinker kit inputs?

Hi all,

Is it possible to add 2 momentary buttons to the tinker kit inputs to mimic 2 of the existing buttons?
Basically, I need 2 of the 4 buttons to be off the pad. Alternatively, I can solder some wires in parallel and add my buttons I need but If I can just add a line of code, I’d rather do that. Take a look at the attached pic to visualize what I need.

Thanks in advance!
