MindGenius is designed to support a single flow direction in maps and therefore does not support linking back down from multiple parents to a single child. If you only wish to give the visual appearance of this in a map however you can achieve the same effect using mental connections styled to look like to normal branch connectors.
To Style the Mental Connections:
- Select the mental connections
- Press "F3"
- Switch to the connector tab and change the settings to match those for normal connectors.
