Default Time depending multi region heater with coupled bc

Dear Foamers,

I have a multiregion setup with a solid (=heater)/air/solid. Radiation heat transfer is needed.
Between solid and air I want to use a coupled boundary for heat exchange.

Before (=single region, no radiation) I could use groovy bc to read data from file like:
        type            groovyBC;
        value           uniform 1000;
        kappa           solidThermo;
        kappaName       none;
        timelines       ( { name curTUpper ; outOfBounds clamp ; fileName "$FOAM_CASE/" ; } );
        variables       ( "TTime=curTUpper;" );
        valueExpression "TTime";
Now I need a compressible::turbulentTemperatureRadCoupledMixed patch for radiation.

When I use:
    type            compressible::turbulentTemperatureRadCoupledMixed;
    Tnbr            T;
    QrNbr           Qr;
    Qr              none;
    value           uniform 1000;
    kappa           solidThermo;
    kappaName       none;
    neighbourFieldName T;
I cannot apply a time-temperature profile (like with groovyBC).

I also tried to set the internal field of the heater with build-in time-dependent boundary conditions,
something like:
internalField uniform table
    (  0   0.0)
    (1000  100.0)
    (0  200.0)
, all without success.

Maybe somebody could give me a hint, how to enable a time depending temperature for coupled bc in this case?
Thank you very much!
