Find and Replace Option for each Line Item Description Box

When entering an HSA invoice (for example), each line description has the employee name followed by the month and year, e.g. "John Smith November 2023 HSA Funding." The next line would be "Jane Smith November 2023 HSA Funding" and so on for the next 200 employees to follow. Can there be a way to search for the word "November" and replace it with "December" so that I don't have to go line by line down the description boxes each month to manually change the word? I can't make a general description because I need each box to show the different employee name. I have this invoice as a memorized invoice so that I don't have to retype each employee name every month that I create this invoice, but it would sure be nice if I could somehow change the month name in every line's description box without having to highlight the word and manually change it, which in itself is a big chore. Thank you.
