How to allow subjects to specify their own group names in the 'pick, group, rank' question type?

Hi All! I'm using the 'pick, group, rank' question type, where subjects are clicking and dragging images into different groups. I'd like for them to be able to specify their own names for the group titles. For the text in the 'items' section, I see an option to 'allow text entry', but this is not allowed for the titles of the groups. Nevertheless, the group titles do allow for piped text. So on a separate page before the 'pick, group, rank' task, I made a set of multiple choice questions with manual text entry, so people can type in group names, and this is piped into the group title grid. However, I would really like these multiple choice questions to be on the same page as the 'pick, group, rank' task, because I want participants to be able to define their own groups in real time. Right now, I only seem to be able to get the piped text to work if the text is inputted on a separate page, because these answers need to be 'submitted' before they can be piped. So what I'd love help with are the following: (1) does anyone know of a way to allow subjects to insert text into questions and have the system automatically pipe the results into a display on the same page, in real time? and (2) in general, does anyone have a method in mind for how subjects can manually specify the titles of the groups while they are doing the 'pick, group, rank' task? Thanks so much!
