Master Zone as push-button

Hello

I would like to control my pump with the master zone.
It starts or stops with a push-button and cannot be pressed during the whole sprinkler time. To stop the pump, I have to press the push-button again.
I can wired the Master Zone directly to this push-butthon via a relay. No problem with that, it is accesible.

Is there any way to configure Materzone as push toggle or something like this?

Thanks in advance
