Custom Image for material preview pane

I’m trying to implement a custom material for my renderer plugin.
I derived it from “RenderMaterial” interface. It is appearing in the material list and can be created from the UI.
The thing I’m looking for is providing a material preview image rendered by my renderer, But I’m not able to find any property, method etc in the interface to set the custom preview image for the material preview pane.
The material preview pane just updates the preview according to the base diffuse color and other material
properties.

Is there any way to provide a custom image for material preview pane?

Thanks.
