Produce events to Single kafka topic from multiple database and collections from source connector

Hello MongoTeam,
We want to setup MongoDB Source connector to produce to Single topics from multiple collection.
Is this possible ?

So far i have tried using
“topic.namespace.map”: “{"^database_pattern_[0-9]{4}[0-1][0-9]:collection_pattern_[0-9]{4}[0-1][0-9]$": "singletopicname"}”,

But it creates multiple topics based on default config of topic creation.

FYI:
we have databases and collection name like :
database_202204.collection_202204
database_202205.collection_202205, …etc

Any help will be appreciated !!
