Is there a way to rename visitor profile ID's, or assign names on the spot?

General questions

Already searched through (possibly not enough) to understand if its possible to have in-line changing of the visitor profile id, or assign recognisable name, so i can organise the returning traffic in more sensible way?

So is it possible to rename this and have it as a name?

  1. is there a possibility to have a “+” sign where i can mark ip’s that i know are bots or crawlers, so they get ignored much faster?

Thank you
