S3 -> BigQuery data transfer: access to s3 filename

[tanguycdls_c]

Hello, i have a data ingestion pattern like this: on S3 every day I receive as a parquet file the current month of data. 

The month and execution time (day the file was created) are only stored in the filename and not as columns.

In Google Bigquery Data Transfer could i keep the information of the filename and have it stored in a column ? I did not find anything like this in the doc. 

I would like to have <my_cols>, filename: (s3://.../.../.parquet)

Thanks
