Hello,

Yes, this is possible in Odoo 18. The recommended approach is to customize the financial report structure rather than modifying the standard Balance Sheet logic directly.

You can add more detailed report lines or sub-lines by configuring the Balance Sheet report, account groups, or creating custom report expressions depending on the level of detail required. This allows you to break down summary figures while preserving the integrity of the standard accounting calculations.

To avoid impacting future upgrades or standard functionality, it's best to extend the report through Odoo's reporting framework rather than altering core report definitions directly.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.
