Whether it has the options, and I didn't see them when using it
yesterday, it is  Not Your Friend(tm). The GUI's do not provide enough
fine resolution, they display nothing of what the actual config files
touched are or what they say, and the automatic writing to disk of
options when selected rather than requiring a "commit" operation is
anathema to a safe network configuration tool.

It has no rollback features, and if you use it on a production
environment, I strongly urge you to put
"/etc/sysconfig/network-scripts/" under a git repository or similar
source control so you can reverse any accidental steps. And I urge you
even more strongly to ensure that you have console access, by local
physical access or a remote KVM console access of some sort, before
you use it, especially if you're manipulating the router used to reach
your local network.
