Agreed!

1. Throw the Advanced Storm Controller out - that gives you a BR storm with phases. You can set the initial size and then it'll just progress.
2. If you want to configure the storm set that controller to Custom - and then use Beacons to override each phase you and to setup. Beacon 1 is a special case that just overrides the first one. Beacon 2 and beyond set where the storm ends up and with what properties.

That should be enough to get you started
