Endpoint cached deployment on MacOS

Hi there,

I was wondering if it is possible to use a preinstalled deployment of Sophos Endpoint.
I know sophosinstaller.zip contains the installer/downloader and Sophos Software Components folder which holds the config for client assignment to Sophos Central dashboard and they need to be kept together.

I noticed that on a MacBook with Sophos installed correctly it has a folder in:
Library > Application Support > Sophos > saas

That contains what looks to be a full installer of around 133MB. I've tried copying the sophosinstaller.zip config into that Sophos Software Components and running that installer, it installs but the device is not assigned to the central platform.

We would very much appreciate a method of deployment that doesn't rely on the Endpoint client downloading significant file sizes
