Adding to existing build directory

[colligant]

If I run ilamb with the build directory as an existing directory, index.html and files like scalar_database.json etc, are overwritten with only the current confrontation. The landing page displayed in index.html goes from having multiple models to only having one. However, clicking on specific benchmarks reveals that the entire suite of models is displayed including the new one.

How to I enable iteratively updating the models displayed in index.html without re-running the entire suite of model/data confrontations? Is this functionality in ILAMB?
