DMF Mapping Staging to Target through code AX 2012 R3 CU10

Hi Experts,

I am working on DMFHCMRatingLevelEntity.

Here the staging field RatingModelId is by default mapped to the target field RatingModel(table HcmRatingLevel) through method generateRatingModelId

I would also like to map the staging field to the target field RatingModelId (table HcmRatingModel) through code. Is is possible?

Thanks,
