Google Charts Sankey - Node text style

[Shafiq Abedin]

Is there a way to change the color of the target node text with style role in Google's Sankey diagram? Currently I have data setup like this:

[Source, Target, Label, Style] 
[A,B,"Test Label", "#ffffff"]

I am able to change the color of the node and links but not the text. 

d3 is not an option for me at this point and the whole idea is to animate the nodes to appear one after the another at its place - hence trying to change the style and re-draw the diagram. Growing the table is not working because the nodes change location. Any ideas?
