"The normal installer", probably not. But that's a scriptable
operation in %pre, just use parted or relevant tools to clear and
create partitions, and the new tool to make the filesystem, and tell
anaconda to use what it finds.

Using anaconda's filesystem creation tools are kind of like pushing a
rope. It kind of/sort o works, except when it doesn't.

Or he can use '%pre". I've certainly done this in test environments
where building up a new boot image or installation CD image was a lot
more work than I wanted to spend.
