You have several ways to do it:
1. Connect to the Shape File, then show the data by styling the Shape file, then you can use "Label to Text" command (see the picture) to convert all labels into MText
2. I supose you are using Annotation to create the blocks with the Polygons Data. You can rename the Annotation Blocks. Simple write Rename in the command line and give a new name for the Annotation Block without the word "annotation". Then explode the attributes of the blocka with the Command Explode Attributes at the Express Tools Ribbon
