No, it is not possible to directly pipe the text entered in a Dynamic Comment Box. However, a workaround is available for such situations. You can create a separate Comment Box question, apply show/hide logic to it, and enable the "Dynamic on Page Logic" toggle. This setup will display the Comment Box on the same page when the desired option is selected.
