Prescribing a current density in a coil in MFH

Hello, I would like to prescribe a given (flat) current density in the single-turn winding of a coil in the mfh module (2D). There only seems to be the 'External current density' node for this, or I have overlooked something. If I do this, and specify a realistic (good) conductivity for the coil, there would be opposite induced currents in the coil, which nearly cancel the externally prescribed current. I can suppress the eddy currents by specifying unphysically low conductivity, but this would create very large electric fields in the conductor. What is the correct way to prescribe a given flat total current density within a coil in the mfh module? Thank you Daniel
