changing render image for brick walls ?

[Anonymous]

i am rending my model, using a standard brick wall graph from the catelogue.
But in the model im making, i want the wall to have a special brick design, three layers dark red brick and then 6 layers yellow brick.
here is a photo of what i mean.

Any suggestions are warmly welcome !
Thanks.
