DPM Project Management | How to move a task from one parent to another parent

Hi,
I have a project with multiple tasks and some tasks have subtasks.​​​​​​​
TaskIdLevel
Task a11
Task b22

Task c

32.1

Task d

42.2
Task e53

Task f

6

3.1

Task g74

Now I've made a mistake, because Task f should be a subtask of Task g.

Is there a way to move Task f, so Task g will become the parent of Task f instead of Task e?
So it looks like below:

TaskIdLevel
Task a11
Task b22

Task c

32.1

Task d

42.2
Task e53

Task g

7

4

Task f64.1
