Your assumption is not correct. The Web UI core admin expects that you've already created the new core's directory and the associated conf directory below it. Since each core may have a much different config, there's no good way to pick the right set of configurations, your schema.xml file which is the heart of your search really must be customized to support your individual use-case.
Personally I'd use the "bin/solr create_core" script command instead. Admittedly the admin UI is tempting, but it makes some assumptions.
