I would be inclined to say that normally nulls can be put in any position within a cipher text at the discretion of the author. This does not preclude given null symbols being used only in certain positions, but I can't say that I am aware of any examples of this being done specifically and I have seen a lot of cipher keys from the 15th century.
One thing I would be interested in hearing Nick Pelling's thoughts on is the varied use of Tironian notes within 15th ciphers, it's not something that I have really got my head around. (There is an example of an early 15th cipher key from King Rupert of Germany in the Gonzaga cipher ledger and I guess it is using some kind of shorthand, but I don't understand quite how it works and it would be interesting to.)
