How to add competitors to cannibalisation

I have added a new Competitor to the map. How can I add take its cannibalisation effect into account?

Click "Map"

Open the Settings

Click "Data and Catchments"

Go to the "Customizations" page.

Turn ON "Include competitors in cannibalization"

Close the settings

You can see that both the map have been updated to take into account the cannibalisation from this competitor: - I now attract 96,091 people in my catchment, instead of 114,484 before - on the map, the area North East of the canal is now completely cannibalised

You can re-exclude competitors from cannibalisation by heading back to the Settings.
