Export topics from MindManager as nested tasks in Mindjet Tasks or retaining map structure

Hello, I started using Mindmanager maps and Mindjet tasks thinking that I'd be able to export tasks in the structure of the map. Otherwise what's the point? But when I export a topic and all its subtopics, I lose all information about where the subtopic sits in the project. This is particularly annoying in that many subtopics are repeated for each topic, so I get multiple tasks called eg "update budget" with no reference to which topic we need to update the budget about.

So my question is how can I export tasks from a map such that they retain any sort of rational structure? Can I create nested task lists?
