How to keep original schema when using ETL tools to load data from mysql to neo4j?

Hi everyone, I'm new to Neo4j. I've installed the Neo4j Desktop app and used the ETL tool (GUI version) for a basic database migration. I managed to migrate several tables from mysql to neo4j successfully. However, I observed that the generated mapping by default adopted camel case (eg. zip_code => zipCode). While it's possible to manually modify each attribute, is there a method to keep the original schema as is such as modifying some config files?
