Default Interface for linking cells other than through faces

I have an application where I want to link the temperature field in a fluid-solid porous region, i.e. linking the gas temperatures to the solid surface temperature through a user defined heat transfer coefficient.

Is there currently a mechanism through which the user can create such links between different temperatures through another mechanism than faces?

I have succeeded in such an application by using 'ghost faces' with zero areas (had to prevent dividing through zero here and there) and then filling in the matrix coefficients just before solution.

Is there an elegant way to do this?

With kind regards,
