Is there any way to support mongo-changestream fullDocumentBeforeChange option through the spark-mongo-connector

Hello community,
I am using spark 3.4.0 with spark-mongo-connector 10.2.1 for changestream interaction. Mongo client support fullDocument and fullDocumentBeforeChange options to retrieve data from the changestream but spark-mongo-connector supports fullDocument only. Is there any specific reason for that? if not is there any way to extend the contract with 1 extra option?
