CSV data mapping to schema

In tgcloud.io in “Load data” tab I have to map data file to vertex and edges. Is it possible to do it automatically do this step? E.g. file name = vertex or edge name and headers in this file = property names.

Let’s go further, is it possible to load files and, based on that, create a schema (vertex types and edge types)? I’m not necessarily asking about the cloud version, but also about the local one.
