Customers experience following error messages due to the defaultWriteConcernSource mismatch between the source and target cluster when restore the snapshot.

Error: Can not restore a snapshot with custom default write concern 1 to a cluster that does not have a custom default write concern.

Error: Can not restore a snapshot with custom default write concern majority to a cluster that does not have a custom default write concern.

Ability to directly change the defaultWriteConcernSource without flipping between w:1 and w:majority will be convenient for the users.

Option location:

Cluster > configuration > Additional Settings >
More Configuration Options > Default Write Concern

Thanks.
