When you have more than one quizz into your Slido, you cannot use each of them in the same Powerpoint. All questions from all your quizz from your slido event are mixed and you cannot run your quiz independently.
The only way to do it is to create as many powerpoint as your number of quiz in your slido, or to run your quiz out of powerpoint integration.
So the idea is to modify the powerpoint integration to allow multiple quiz to be run independently.
