From the Panorama device, you can provide a Path for all the firewalls managed by that Panorama.

If you select to see all the Firewalls, not only the directly connected devices (do it clicking on the three lines icon on the Devices view) you would see all the Firewalls, and you can even select and Autooprocess on the logs, so you do not need to get into them daily.

Later on, in your project, you can import the Panorama config and define in your log connector the Device Group and the devices within that DG for the ML and RE.
