I would like to bulk edit my labels for auction lots

[picker57]

This feels like it should be easier. The attached screenshot is of my business document that I would like to edit. I run an auction company and this is the document for me to put labels on the auction lots. I had another company owner that helped me learn my business, and she shared the document with me. In the past, when I have wanted to make changes, I just cut and paste the information, but with a document that is set up to accommodate auctions with 1000+ lots, it can take a lot of time to change the business name or renumber. I assume it originated as a mail merge label or table or something that the creator input the company, told it to number 1-1000 and Word did the rest. Any thoughts for how I can simplify this some?

Thanks so much in advance!
