When using a calculated property, there is no way to override this property and the property is read only. We are using item types for pay items, and since there are so many possible scenarios to calculate a quantity, currently users will need to manually key in a value, and in different columns we automatically calculate things like length, area, and volume. It would be nice if we could auto-populate a property, but still give the user the ability to override that value and key in their own value. This would preferably be a setting within the item type property so that we can still control which properties are read only and which are able to be overwritten.
