Supports for a lip on a cylinder

I have a very simple shape - a cylinder with a band at the base and another band near the top. When I slice it supports will be needed for the red edge and they will start from the base of the cylinder.

Is there a way to have supports start closer to the red edge instead of from the base of the cylinder? The red edge protrudes out to catch a clip so I want it to form a 90-degree angle with the cylinder. Same goes for the blue edge.

OpenSCAD code for the shape is attached as an image.
