Cubase 8.5 preferences problem


I have made a terrible mistake, I apply a process at one sample (the reverse function) by clicking on “don’t ask again” , then I missclick on the windows who ask if you want apply this at all sample, now at every Reverse on a sample, this apply to all, and impossible to find where can I change this preference.

Can someone explain me where found this please ?

Thanks !

Not at Daw to get this exact but it’s something like Preferences/Audio/Editing/On processing shared clips. Select the option you want from the drop down.
