How to place a decal image in a multi curve surface

Hello everyone, I’m using Creo 8.0.9 and I need to create a sticker adapted to the surface, but for that I’m using a decal.
When the sticker is flat, applying the decal is easy, but when it’s curved, it becomes very difficult.
Is there a better method?
Or is there any parameter in the planar mode that can be set to automatically adapt to all surfaces?
