ABC Group is configured as company with its own COA in odoo

XYZ private limited is configured as subsidiary under ABC Group, with its own COA

While running Trial Balance Report for All companies in Odoo, the report shows same ledger (e.g., Debtors) value is shown for ABC group and XYZ private limited in two lines separately.

We need one single line to show ledger wise cumulative value (e.g., Debtors) for ABC Group + XYZ private limited.

How to do it? Is there a plugin or workaround? Please suggest.
