So I'll add some more context to the above:

12345 Sourcing Issue Bob / Karen / Rich
10/6 Karen: You guys failed to source the materials for this PN
10/6 (Factory Person): Oh sorry about that, you know how it is
10/7 Bob: Yeah, blah blah blah you guys do this to us all the time
10/9 (Factory Person): OK we finally got the materials, now what?

55432 Part Burned Down Customer Location! Julie / Mike / Steve
10/1 Julie: Just heard that this part caused a fire at a customer location
10/2 (Factory): That sucks, you know Chinese parts!
10/3 Julie: No seriously, WTF Batman.

XYZ Company Needs New Label Bob / Carl / Susan
9/29 Bob: Company requests their zip code on box label
9/30 (Factory): That's crazy, who needs a zip code on a label
10/1 Bob: It's what the customer wants, do it
10/2 (Factory): OK. If we have to

So in the above 3 post examples I would want them to split out into documents based on the "SalesPerson" label (the first name in the 3-name splits). So in the three above examples there are only 2 sales person topics Bob and Julie so...

10/1 Julie: Just heard that this part caused a fire at a customer location
10/2 (Factory): That sucks, you know Chinese parts!
10/3 Julie: No seriously, WTF Batman.


Now there could be 10,20,30,100 topics per sales person spanning several pages. In general we have about 5 sales people to do split this document into.
