Transfer function on voltage source

Hi,

I am new to Pyspice and I am moving our LTSpice simulations to PySpice. In that simulation we have some transfer functions defined as voltage sources with a transfer function like this:

I=V(A_IN) MAG FREQ=(34000.0,-0.386765E-03,-0.191481E-03)(34050.0,-0.415016E-03,-0.187603E-03)

Is it posible to implement this in PySpice?

Regards
