How can the system automatically add previous Case history lines of the same customer to the "RELATED CASES" TAB?

Hi Team,

We would like to implement the following feature.

When entering a customer into the Case screen => If that customer has had previous Cases, the system automatically adds rows of the previous Cases in “RELATED CASES” TAB and are arranged in CreatedDateTime of Cases.

I created Event RowInserted but haven't achieved results yet.
Please advise how to do this.

Note: Acumatica Version 2020R1

Best Regatrds,
