Pause and accent

Is there a way to pause and use a accent sound at the same time without having to push both buttons?

Probably not.

Buy a Digitech fs3x footswitch. I have the fs300 (old version) and the right switch is wired to act like the two others pressed together.

Another method is using a MIDI controller with multiple assigns pr switch. I use a PrimovaSound MIDX20 to tap tempo while playing a foot hi-hat at the same time.

En todo caso tendrias que comprar una pedalera adicional con dos pulsador, personalmente yo utilizo la Boos dual Foot switch FS-6. Desde la bb puedes configurar.
