l-inc: Besides, referencing the entries by label is currently problematic with multi-pick lists anyway if the labels and values differ. That's because of the inconsistency between the multi-pick and single-pick lists when handling value that consists of key-value pairs. For the single-pick lists, the keys and values in the key-value pairs become storage keys and values respectively, whereas multi-pick lists store the key-value pair as a single object, which cannot be used for the purpose of retrieving the labels.
