How do you add additional positions to Gradient Node?

[pegot]

In Octane stand alone there is a bar graph with "+" and "-" buttons to add and remove additional gradient positions (see attached screen shot).

I do not see this in the Blender plugin; how can I add additional position values to the Gradient Node in the Blender plugin?

Bump - I'm asking a pretty straight forward simple question here. Is this currently possible in the Blender plugin and if so, how? Maybe I'm just overlooking something basic but I can't find out how to do this as easily as it is accomplished in Octane standalone. I am trying to make a colored ramp texture.

Thanks!
