[Users] Chunked checkpoints with unchunked HDF5_3D output?

Hi. Silly question time:

I'd like to write some grid functions to disk as HDF5 3D files that are *unchunked*, but one per output time step. This I'm doing by setting the following parameters:

IOUtil::out_mode = "onefile" IOUtil::out_timesteps_per_file = 1

However, an unexpected (to me) side-effect of this is that my checkpoint files are now also unchunked, which leads to longer recovery (and occasionally failure).

So ... can I have chunked checkpoint files, but unchunked everything else 3D using CarpetIOHDF5?

Thanks,

Bernard
