Is it possible to remove the hardcoded filenames?

The structure of the filenames is hardcoded into the Python code. To allow use with different ways of outputting the files from the UM, or even different climate models, could the structure of the filenames be specified in rose-app.conf?

Start by locating the Python code that hardcodes the output filename structure and the configuration handling for rose-app.conf. Trace how filenames are produced for the current UM output, then determine the configuration shape needed to support alternate output formats or climate models; done means those structures can be selected without changing the Python source.
