I think custom commands are what you are looking for. Take a look at
custom_commands-sample.json and the files in config/custom_commands. The
mechanism is described at https://genieacs.com/docs/.

In my understanding, an object is an instance of a subtree of the
parameters tree. For example (i don't know the exact parameter path from
memory):

InternetGatewayDevice.Dynmasq.StaticLeases.1. contains all parameters for
the first dhcp static lease.
InternetGatewayDevice.Dynmasq.StaticLeases.2 contains all parameters for
the second dhcp static lease.

So basically InternetGatewayDevice.Dynmasq.StaticLeases. is an object for
configuring dhcp static leases.
