CDO

Hello
Is there any way to prevent cdo commands from renaming dimensions between the input and output files? For instance if I use splithour on a file with multiple hourly timesteps I end up with a series of hourly files with completely different dimension names from those in my original file. These files are then incompatible with my existing software. If it isn't possible to prevent the renaming, is there a work around to reset the dimensions in the new files back to their original names?

Thanks for any advice
Ian
