Found a plugin that looks like it does exactly what we need, allow to choose a template for the category, called Custom Category Template. It should do the trick, but somehow not working in Interface theme. I changed to Twenty Thirteen and worked.

When it doesn’t work, support issues all point to templates that do not use the normal WordPress template hierarchy. As well, the plugin uses the native category_template hook.

Does Interface theme use WP hierarchy and native hook? Just trying to narrow the issue in case it might be with another plugin.
