Loop & Merge on a matrix table with display logic

Hello everyone,
I created a matrix question with 7 statements in the rows and a 5-point scale in the top (very important to not important at all). For the statements that respondents find very important or important (Top-2 box) I would like to ask the follow-up open-ended question about 'Why they find this important?'. However, I only want to ask this question maximum three times and the statement should be inserted in the question text so I know which statement their answers refer to.
I have now created a new block with the question "Why do you find: XXXX important? ". I put Loop and Merge on this block and the loop is based off the Marix question. I have also selected Randomize loop order - and present only 3 of the loops. However, for selected choices I can only choose one answer: very important or important and not both of them. Is there a way to solve this? Or is there another solution to my issue?

Thanks in advance,
Christel
