The EL7 partitioner is a complete disaster and I regularly bitch about it on twitter and irc.
Aye. It's annoying that the text mode installer can't manipulate partitioning at all -- they lost that when they made the installer "better". If it weren't for that I'd never use the graphical installer.
Another option is to boot in a Live CD and do you partitioning from there either manually or via Gparted and hope these changes will be picked up by the EL7 installer so you can just use them as they are.
Similarly, switch to VT 2 (Alt+Ctrl+F2) just before going into the partitioner and do whatever you like with fdisk (etc) then switch back to the graphical installer and upon entry the first time rescan the drive(s).
