Using a previously obtained electric potential in the Nernst-Planck equations interface.

I've calculated an electric potential distribution using the electric currents interface, and now I need to use that electric potential in the migration term of the Nernst-Planck equation. I’m not sure how to couple both physics. I thought about simply typing V for the electric potential in the dependent variables of the Nernst-Planck equations interface, but I don’t know if Comsol would recognize it as the electric potential I obtained previously. Also both analyses are time-dependent, so I need that for a given moment in time the electric potential in Nernst-Planck equations interface is the electric potential calculated with the electric currents interface for that specific time. I’d really appreciate if someone could help me with this.
Thanks in advance.
