I had the same problem, and I solved it passing trough Substance Designer,chaining the bump with a 2DTransform node, and re-importing the image as a substance.
But I do strongly agree that there should be the chance to add a transform node to everything in SP (like stencils, images, effects, etc.)
...now that I'm thinking about it, maybe I can just make a substance and apply it as effect to the fill layer, let me give it a try!
