Does anyone know how to change the zones on a Optima XM Alarm system?

We currently have an Optima XM system in a property we have just moved into.

We would like to change the zones so that zone 1 is the kitchen and zone 4 is the lounge. zone 1 is currently in the lounge and zone 4 is the kitchen but we would like to swap these. Please can anyone help with this at all?

We have checked the Optima XM Manual and there is nothing in it about changing zones. I wonder if this is possible?

Many thanks
