Way to exclude records from Duplicate Identification

Hello,

We have a requirement here where we want to exclude matches for those two records which are having a particular source_system.

Meaning in a duplicate Set lets say we have 3 records,
Two of them are having same source as source_1 and third record is having source as source_2.
now our requirement is to exclude the match of two source_1 records with each other but both the source_1 records should match with source_2 in different match_set.

Need help on how we can achieve this in Oracle Fusion CX Sales Cloud Service Customer Data Management.

Thanks,

Anurag
