How to get the last scan date (not CM or re-evaluation)?

Hello everyone,
I am using IQ Server with Continuous Monitoring on the released applications so when I look at the reports, they are always dated less than 24 hours ago.
But I need to know if the BOM is really the BOM of the released application, so if the scan was made after the last release date. I tried using /api/v2/reports/applications/{internalId}/history but i only get the last 100 results so with CM every day I can only get 3 months old reports and even less if there are reports made on other stages.
Is there any way to get this scan date?
Thanks for your help,
