Is it possible to add a preview image of light cone as on the lower-right corner of Characters UI?

For this preview varies for each light cone, it's a hard work for us to do this manually.
Or maybe it's okay to return an additional value indicating the y-offset, e.g. for 在蓝天下(as shown above), it's approximately 40%, instead of returning an image like above.
