Those controls are not meant to be changed by scripts. They 're automatically saved and restored between sessions.
If you insist on changing them (I don't know if this will even work), these are their IDs:
Release name: ID_TEXTCTRL4
Release binary output: ID_TEXTCTRL5
Release objects output: ID_TEXTCTRL6
Debug name: ID_TEXTCTRL3
Debug binary output: ID_TEXTCTRL1
Debug objects output: ID_TEXTCTRL2
