Bullet Chart by OkViz- Conditional format

Hi All,

I am using Bullet Chart by OkViz

I have conditionally formatted my bullet chart  as below:
IF actual value is less than Plan Value -> Red Colour for Actual Bar

otherwise Default Green.

Is there a way I can additionally create one more condition like If there is no Plan, the Actual bar should be shown in Black Colour?

I Could see only one conitional colour formating option with this visual. (that allows me to select if Actual is >,>=,<,<=,= to Plan).
