Smart components with bipolar control?

Is it possible to setup a smart component property so that it interpolates from Negative to Master to Positive?

I want to create a rotation property, so that the Master layer is the default position and relative to the master, there’s a Positive Rotation Layer and Negative Rotation Layer.

A smart component can have intermediate layers. So you set up the smart glyph with the negative and positive layers and add intermediate layers for the master outlines.

Is there a tutorial explaining using Intermediate layers in Smart Components? The Intermediate option is greyed out for the master layer.

You fist build a smart glyphs with only rotate R and L. Then add new layer and make it intermediate.

I see. So, layer L should be the master, correct?

Yes.
