Use case:I have an existing object with an attribute (e.g. Object or User type) with 2 values in it.I want to update my Object and add a 3rd value.Current Situation: the PUT API (Object / Attribute) will remove the previous 2 values, and will replace them with the 3rd value only.It will be nice to add an optional param: e.g. Append = True to the Attribute Value, so that the end result will be: the Attribute is having 3 values.
