Moving tasks from one Task Group to another

You can use  Copy & Paste feature to transport tasks from one Task Group to another one. 

Simply select the tasks you want to copy, right-click on the mouse, and select Copy. After that, go to another Task Group, right-click and press Paste.

Woohoo, it's done! :) 

Just so you know, you can simply delete the tasks in the first group if you don’t need them anymore.
