[Wien] Is it possible artificially shift Fermi level for optical calculations?

[Martin Gmitra]

Dear Wien2k users,

I am dealing with a slab system having a significant dipole moment.
Therefore, there is a Fermi level offset. I would like to calculate
optical properties of the system while I need to artificially shift
Fermi level. Do you have an idea how to do that?
