You can append shortcut paths to the Templates directory. The added paths appear the next time you launch MotionBuilder, and remain available for subsequent MotionBuilder sessions. 
To add a shortcut path: 
- In the Asset Browser, right-click in the Browser pane and select Change template directory from the context menu. 
 
- Navigate to choose the shortcut path you want to add in the Open directory dialog box that appears. 
 
- Click OK.
