wallHeatFlux function object write frequency field/statistics

When using the wallHeatFlux function object, the entire field is written to disk at the same frequency of calculated min, max and averaged values, leading to a large amount of space used on disk.

Is it possible to have the wallHeatFlux written to time data in the main folder (not in postprocessing) only with the chosen frequency from the main writeInterval in the simulation and a separate frequency for the statistics (columns file)?
