EA Sports WRC Extract liveries from EA WRC

[NickyHolloway]

Hello everyone,
as a total novice about creating custom liveries, i want to ask if anyone know a mode to extract the official liveries of the cars (with official liveries i mean the standard ones created by EA) and than modify them (for example i would like to add some sponsors to the blue Ford Fiesta WRC2 of Fourmaux). Is it possible?

Thanks to those who reply!​
