Apply scoring for only some questions in Loop & Merge

Hi everyone,
In my study, participants need to read and go to the next sentence during a reading phase. To make sure that they are paying attention, I have included a few filler nonsensical sentences and they must indicate that they are nonsensical instead of clicking the next button. I used the scoring feature on those to give a wrong answer feedback if the partipant choose "next" instead of "nonsensical". These fillers need to be randomized and appear in between the actual sentences. For the actual sentences, I don't want to provide a feedback because the study would become too long.
I would like to know if it is possible to use loop & merge function based on two types of questions, one that would require a feedback and another that does not ?
Thank you!
