"Descriptive text" questions do not appear in data (with the modern exporter)

Hi,
With the "legacy exporter", "descriptive text" questions appear in my dataset, with values 1 indicating that the question was displayed and empty values indicating that the question was not displayed to the respondent.
With the "modern exporter" the descriptive text questions are totally omitted, and I cannot even find them in the "Data & Analysis" panel anymore. Is there any way to force the modern exporter to also consider this type of questions?
I know that I could define embedded data to indicate whether a question was displayed or not, but it would be easier to simply get this information directly. For instance, assume that I have a block with two descriptive texts (these could be "treatments" dedicated to affect subsequent answers) and I want to display one to each respondent randomly. That could be implemented with the block randomizer. How would I then know which question/treatment was displayed to each respondent without having to look at each recorded response individually?
Thanks very much.
