Can Audit report capture backdated changes

As we all know, any changes that need to be captured in audit reports must first be configured by selecting the corresponding audit objects and attributes in the 'Manage Audit Policies' page.

Since this page does not provide any start or end date fields, my understanding is that audit tracking only applies during the period when the 'Audit' option is enabled for the selected objects. In other words, it does not capture any changes that occurred before the audit was activated, nor does it track changes made after the audit setting is disabled. The system does not support backdated tracking or retrospective traceability.
