Change the structure after a BecomeChild

Hi,
I’d like to know if there is some way to change the stucture after i grouped some notes in the mindMAP with become child function.

I mean for example I’ve 3 notes, 1 note is main and I use become a child of the other 2 notes with the note number 1.

So I’ve the note 1 and note 2 and 3 are children of note1

Now I want to change and I want Note 3 become a child of note2 and note2 be always the child of note 1.

I didn’t find the way to modify this status,

Can you help me pls?

Thx

Just simply drag the 3 on the 2.
