Convert one label attribute (label_store, symbol, or description) to another.
        Input arguments:
        - inplace - If True, sets the object attribute. If False, returns the value.
        - overwrite - if True, performs conversion and replaces target field attribute even if the
          target attribute already has a value. If False, does not perform conversion in the aforementioned case.
          Set to True (do conversion) if inplace=False.

        Creates mapping df on the fly based on ann_label_table and self.custom_labels
