Apparently the receiver hasn't changed since wog 3.58.
Perhaps with !!OB:C it would be possible to change the monster's settings without resorting to UN:O, UN:I or !!PO.
But it seems to be more difficult than just removing the monster and reinstalling it.
Please note that monsters with MO:A B M settings have a limited number range of 0..255, exceeding this number may cause errors, or some monsters will have the same settings.
