Can I populate an acronym list that varies by user

We have different offices that want different acronyms to show up on our log key.   There are over 30 acronyms that I currently have hard coded into the log key as text entities. Can I build an acronym list from a Lookup table maybe, so the user can select certain acronym list groups, depending on their needs?  I want them to be alphabetical, so it is hard to just tack onto the end.  I don't want to make 5 different versions of the log key template.
