Adding cycles to UserData Field

I have this userdata cycle field with several options (cycles).
But I want to change those options depending on other functionality.
Reading posts here on the forum, I think I must remove the ud field and then insert it again.
However, when inserting, the ud field is always placed at the end of my ud.
How can I update the cycle field, but do not change the position of the field.

Here the working code, which updates the cycles, but places the field at the end.

        for id_, bc in obj.GetUserDataContainer() :
            rid = id_[id_.GetDepth() - 1].id
            if (bc[c4d.DESC_NAME] == "Render Preset") :    #get cycle options
  
                cycle = bc[c4d.DESC_CYCLE]     #basecontainer with cycle options.
  
                for i in cycle: print i		     	#show options for debug information
                cycle.SetData(4,'Lowlow')     	#overwrite option 4
  
                bc[c4d.DESC_CYCLE] = cycle	      #write back to container
                
                obj.RemoveUserData(rid)		      #remove ud
                c4d.SendCoreMessage(c4d.COREMSG_CINEMA, 
                    c4d.BaseContainer(c4d.COREMSG_CINEMA_FORCE_AM_UPDATE))
                
                obj.AddUserData(bc)	        #add again (but now at the end?
                obj[c4d.ID_USERDATA,rid] = 1    #set default

I messed some indexes. Thanks to one of Scott's posts it is now working.
No need to remove and re-insert.

                obj.SetUserDataContainer(id_, bc)
