Hello Avni,
Unfortunately, the Reltio Load date is not an option to configure within a survivorship rule. Recency only uses either the Crosswalk's Update Date, Source Publish Date, or Single Attribute Update Dates.
Please raise an enhancement request if you would like for PM to review.
As an alternative:
In the integration layer, you can send a system timestamp to a new attribute to designate when the record is attempting to be updated from the integration layer. Then, you can use this new attribute to drive survivorship bases on the latest date.
