So my project looks like this :

```
A--B--C--D master
      \
       \-E--F--G--H topic 1

```

And i would like to re base a part of the topic branch so that it looks like this :

```
A--B--C--D master
       \  \-G--H topic 2
        \-E--F topic 1

```

Is it possible and if yes can you guys help me ? Thank you !
