Need the ability to export/ import a questionnaire from Test into Production that comes across with all of the question configuration and branching logic.

It is currently possible to export the question types, wording and response options from Test and upload it into Production, but it doesn't bring across all of the details - eg columns, rows, and connected questions, so you end up re-building most of the questions manually.

You should be able to build it, test it and copy it across without any additional tweaking.
