Not yet James, as per this related thread.
If you have a finite set of users in mind (unlikely, since you're trying to use type ahead) you might consider using a multi-select drop down with one entry per person (and -- bonus marks -- using their GUID as the value in the drop down so you can do other cool $$USER.ID things with it),.

@Kyna Baker - inactive‚ to find that previous thread, recalling that in Classic Community that I'd put an image of a silver bullet cartoon on my post (and mentioned that in the text), I tried your tip from yesterday and searched in 0ne for "silver AND bullet" (meaning I needed both terms in the post), and presto! Two hits matched, and the first one was the one I wanted. I will definitely keep using AND in my searching -- thanks for pointing it out!
