I missed this response to my old question. I am looking forward to see this implementation. Thank you for your great works.

I have also some suggestion. Is it possible for an user to define new objects and corresponding algebra without touching internal structures of FeynCalc? For example, metric tensor in (t,z) or (x, y)
space :
g_\par^{\mu\nu} = diag(1, 0, 0, -1), g_\perp^{\mu\nu} = diag(0, -1, -1, 0)
such that
g^{\mu\nu} = g_\par^{\mu\nu} + g_\perp^{\mu\nu}

Four vectors and Gamma matrices are decomposed accordingly. These structures appear in QFT calculation in presence of a background magnetic field.
