[CentOS] Anaconda : MBR vs. GPT

I've always been a bit puzzled by the fact that Anaconda provides no option to
manually create a partition table and specify if it's MBR or GPT.

>From what I can tell - at least under CentOS 7.x - Anaconda will default to
MBR, even if I specify a BIOS Boot partition. Maybe it switches automatically
to GPT if the disk size requires it ( > 2 TB IIRC) though I don't have any
corresponding hardware here to test it.

Is this documented somewhere? Or is there a nifty little trick to tell Anaconda
to prefer GPT partition tables?
