[Therion] Revise command: how to remove persons later on

[Benedikt Hallinger]

Hello,
i currently have the following immutable centerline:

--------- immutable.th --------
survey immutable
   centerline -id zug_1
     date 2014.11.15
     team "Some One" notes
     team "Some Other"
     team "PersonWhoDidNot Attend"
   endcenterline

   input extensions.th
endsurvey
--------------------------------

The additional file "extensions.th" could be modified.
I am able to add and change existing persons in the centerline, however i 
wonder how i can delete a person afterwards from the revise block:
-------- extensions.th --------
revise zug_1
   team "NewPerson added"           # new team member
   -team "PersonWhoDidNot Attend"   # team member i do want to delete: HOW 
DOES THIS WORK?
endrevise
-------------------------------

i hope such a possibility exists somehow, or if not, if someone skilled in C 
could add this please?


With best regards,
B. Hallinger
