If this CA has ordered individual paint options before, not the options like Frozen Brilliant White, etc... they should be aware that they need to submit a form to request that your paint color of choice be approved by BMW. As was stated, choosing Voodoo Blue is not going to be an option in the system. This request/form can't be submitted until after your allocation is available.
I requested Marina Bay Blue and my current build shows Portimao. This is just how it works because you can't submit a build without a paint color to choose from and the Individual paints will not be an option in the system.
If they know how to submit a form/request to BMW, they should be able to take care of you without any issue. Once they get the request over to BMW, you can then continue to use the same production # to track the process. You can see a detailed explanation of the codes they use here:
