I have a similar need to this so have supported this with votes. I frequently set up polls in workshop sessions where I want to list comparative answers in two columns (an A/B sort of response test).

It'd be a great feature for people to be able to enter a response and then allocate it to a column (or title) so that the responses appear in a columnar format.

Use case example: Asking people to brainstorm what (a) went well and (b) could be improved.

In a workshop session, it's a better flow to have this as a single discussion, rather than breaking it up into two separate questions.

This could also apply to multiple columns, hence I've added it to this suggestion here. (e.g. What are the benefits of option A, B or C (with all results displaying on screen on columns).
