For example, here is a rational polynomial: $ $ \frac{8 z^2}{8 z^2-6 z+1}$ $

If I using Apart directly, the result is: $ $ -\frac{1}{4 z-1}+\frac{2}{2 z-1}+1$ $ but if I want to using $ z^{-1}$ as the variable, the partial fraction expansion should be: $ $ \frac{-1}{1-\frac{1}{4}z^{-1}}+\frac{2}{1-\frac{1}{2}z^{-1}}$ $ Is this possible in Mathematica?
