Check BmtScriptPlayer - it's a command line tool that can playback FM transaction logs.
When you do something in FM, it's recorded in the transaction log (XML). You can modify a column description manually, check the transaction log and mimic the same actions from your description file. You could probably generate a python script in chatgpt to translate your description file to the XML log that can be read by the script player.
Make sure to backup your model before running the script ;)
