I assume there is not formula reference for this. Is there anyone with prebuilt formula that will identify when to use the s, ‘s, or es on a name? To comply with the standard English rules here: https://www.merriam-webster.com/grammar/what-happens-to-names-when-we-make-them-plural-or-possessive
I’m sure I could take 2+ hours figure it out, unless you by chance have it 😀
