Hi Mike. Thank you for your inquiry. Here is some information regarding the way in which this currently works. When writing from the Mindjet desktop application to SharePoint tasks, we support these fields, including: Topic - Title, Priority (Only 1-2) - Priority, Progress - Percent Complete, and Start Date.
After the task is sent to SharePoint from Mindjet, it can then be modified in SharePoint with information such as Resource, Description and Notes. It will then appear in the Mindjet desktop when the SharePoint query is refreshed on the desktop application.
