How to override financial_statement.js?

I created my customize report and I need to override the financial_statement.js. Could someone help me?

Update: I already override the financial_statements.js, but when I add default value for finance book. It doesn’t display in the report.

Any luck with this? Having thesame issue when trying to set the finance book default.

Still haven’t resolve this but my alternative solution for this is I added another finance book filter and just hide it. Hope this would help you.
