[CentOS] CentOS 7 : create RAID arrays manually using mdadm --create ?

Hi,

When installing CentOS 7, is there a way to

1. leave the GUI installer and open up a console
2. create RAID arrays manually using mdadm --create
3. get back in the GUI installer and use the freshly created /dev/mdX 
arrays?

I tried to do this, but the installer always exits informing me that he 
can't create the RAID arrays (since they're already created, duh).

Any suggestions?

Cheers,

Niki
