At present it is cumbersome to run parts of the summa domain that are not in contiguous order in the input files. One must either split the domain to create new subsetted input files, or run a batch of single gru/hru runs that must be recombined after the fact, or reorder the inputs so that a contiguous gru run can be done. Having a run mask as part of the trial-params file would make sense (not unlike the VIC active-cell parameter in the soil file). It's not a completely simple enhancement, as it affects both the run loop and how the outputs are written. But not hugely complicated either. It's a usability enhancement.
