Changing Attribute Tag Names

I am wondering if there is an easy way to change multiple different block attribute tag names without having to use BATTMAN. My issue is that I have over 400 different blocks which all have attributes with tag names like 1, 2, 3, 4,...etc. but I would like to change these attribute tags to what each number actually represents rather than the numbers (i.e. 1 -> Part Number, 2 -> Part Description, etc.) I can't export the attribute tags because these attributes are constants and not considered true attributes. We only use these constant attributes so that we can export the data for parts list but we don't want people to have to constantly get the attribute editor pop up every time they insert these blocks.I am using AutoCAD 2025.

You can specify an attribute to be a constant in the attribute definition of the block.

If the issue is the attribute editor displaying upon insertion, there is a system variable to disable that. This variable would be the ATTREQ system variable. It can be set to 0 (zero) to assume the default values of the block. This could be configured using an ACADDOC.lsp file stored within one of the paths listed in Support File Search Path settings found in your Options dialog.

If the attribute numbers are still needed to be changed, you will want to change all of your source blocks (assuming these are stored drawing files). After the source blocks are updated, redefining them in your drawings should rename the attributes. However, an Autolisp routine could be created to read a text file to associate the block name with the necessary attribute names to change. If this is your route, you may want to ask that in our Autolisp forum.
