contact resistance in PDE mode

I am trying to model the thermoelectric element using the COMSOL PDE mode. I want to include the contact resistance at the metal-semiconductor interface. I defined the interface as the identity pair. However, the only interface condition available is
n.(gamma1 - gamma2) + qu = g, where gamma is the flux of the dependent variable u.
It doesn't allow me to include the jump in the dependent variable "u" which will occur if contact resistance is present.
I read the documentation of conductive DC mode and it has the capability to include contact resistance at the interface which it model as the
n.J=-sigma *(V1-V2)/d
Is there a way to include this above equation in the PDE mode.
Thanks
Vivek
