You might be referring to the tag. There is a such thing as a nameplate, but it is usually associated with push-buttons and switches. If a footprint block contains no predefined attributes, and you insert it via the Schematic List, the software pulls from a group of .DWG files (a.k.a. blocks) in the root of the panel folder which contain minimum necessary attributes for the type of footprint in question. AutoCAD Electrical will merge this block into the footprint block and the two will become one. The block the software "merges" with the footprint contains the proper attributes to hold the data that is being transferred in from the schematic. It actually only needs to push in attributes for visible data, so such things as manufacturer name, catalog number, assembly code, etc. will be stored as hidden xdata. Usually the attributes that are visible are such things as the tag (P_TAG1) and the rating (RATING1), so these are the most popular attributes that are pushed into a footprint. By default the software will position the merged block at the base point of the footprint.
Understand that the footprint symbols/blocks supplied by Autodesk come as-is from their manufacturer. Most contain no attributes, though some, like AB pilot lights for example, might include an attribute named COLOR. Terminal blocks are the exception. Autodesk pre-loads terminal footprints with attributes so they can function properly with the Terminal Strip Editor.
Now, with that understanding as a backdrop, here is how you solve the situation you describe. Simply open the file for the footprint in question and use the ATTDEF command (yes, a plain vanilla AutoCAD command) to add an attribute named P_TAG1. Position this attribute where you wish and perhaps set a default text height. The text height can be adjusted later using the Change Attribute Size utility. Now, save the footprint block/file. Hint: If your drawing contains previous versions of this block you can use the Update Block utility to update existing blocks that have already been inserted to the version you saved that contains the added P_TAG1 attribute. The Update Block utility offers the option to perform this update project-wide, in case you have used this block on multiple drawings within the same project. I sell an add-in utility for AutoCAD Electrical that can perform the Update Block function system-wide, so all projects that contain an older version of a particular block can be updated automatically.
Note: You could have used the Symbol Builder to add the attribute but that is overkill when you only need to add one attribute.
