Closing SoapUI without Question "Exit SoapUI?" popup

Hello !

I am searching for an parameter (but English is not my main language) to close SoapUi without the Question "Exit SoapUI ?" in a popup.

It's not user friendly for me and it's what I don't like in this software :

I think it's unecessary because if something is not saved, SoapUi ask for saving. So if we click on close, I just want to see SoapUi closing.

Do you know if it's possible ?

Thanks,

Annie.
