Boundary condition problem in comsol 3.5a

My problem has as follow: I have a transient model that solves the continuity equation coupled with the Poisson. The boundary condition for the Poisson equation is V0. But this boundary condition is calculated by the solution of a very simple circuit equation V0=Vsup-I*R. I is the current that arises from the solution of continuity and Poisson, R is the resistance and Vsup a constant voltage. How is it possible to introduce the boundary condition V0 in the Poisson?the problem is that in every step this BC changes. It is time dependent but it depend on the solution of my model (that includes the continuity and the Poisson...).
I would appreciate any suggestion
