Weather Pattern Blueprints

Until recently I never realized that we can create changing weather patterns in Railworks. In fact, this feature was a part of the original Railsimulator program. There are several weather pattern blueprints associated with the HSC route that change conditions during the scenario. In other words, the scenario might start out sunny; after a pre-determined time change to cloudy skies; and finally after another pre-determined time change to rain (or any combination we design).
Here's the link to the RW Wiki regarding Weather Pattern Blueprints:

I haven't been able to determine if the weather pattern must be created as a part of the route creation process or if new patterns can be added as needed. I was able to use one of the HSC weather patterns with another route after editing the scenario with RW Tools.
