How to insert a workplane into a object and define Neumann boundary on the workplane.

I am studying diffusion by using COMSOL. I have a large object and I divided it into smaller parts by defining workplanes and using these workplanes to do partition of the object. After partition, I can define concentration on these planes, but can not define flux on these planes ( as you can see in the attachment, when define fluxes, the plane 6,9,12 are not applicable.). I know this is because these planes are interior, so fluxes can not be defined on them due to continuity considerations. I also know that when finalizing geometry, we can change the method from 'form union' to 'form assembly' to change the interface from interior to external, so we can define fluxes on it. But my question is that, at the first step, I have a large object to be divided instead of several small objects to be combined together. Does anybody know how to insert a workplane into a object and define Neumann boundary (fluxes) on the workplane? Or maybe divide a large object into smaller ones and therefore can define fluxes on the interface. Thanks a lot!
