how to change the start of a tiled texture?

CasualEvolution

Hi, in tiled textures, the image repeat beginning from left side of object to right side.
I dont know if its possible, but here my question: for some objects I need that the tiled texture, start from the right side of the object and extend repeating the texture to left.
I tried to change the width of the object to negative and flip the texture too, but neither works.

Any ideas?

Thanks

I found a work around! rotate object 180 degrees and flip image vertically
May be there are a more elegant solution, but for now this works!
