Trend Edge tags on central Ignition gateway

Hi Ignition Experts,
I have a requirement to trend Edge gateway tags (historical and real time) on a central Ignition gateway.
I tried setting up Edge Sync services, but discovered that this only writes historical Edge tag data that is expiring from the 7 day window on the Edge gateway.
Is there a way to achieve my goals using Edge Sync services, or do I need to pursue another strategy ?

Thanks,
Damien
