How do I manipulate the object? It is read only.
And using the builder functionality seems very cumbersome since I will have to init all the new fields with the fields of the existing object.
var item = GetItem(itemID); // Get Item info from Square
var object1 = new CatalogObject.Builder(type: "ITEM", id: itemID)
.PresentAtAllLocations(false)
.AbsentAtLocationIds(locationList)
.ItemData(item.ItemData) // assigning existing item information to newly built object
.CategoryData(item.CategoryData) // assigning existing item information to newly built object
//more fields need to be added here
.Build();
