Rather than create a separate axis for each letter you type, you can separate words or sentences created in the Text menu so that each letter can be individually manipulated.
(a) Root axis for word (b) Root axis for letter (c) Offset per letter (d) Letter geometry
To separate text:
Each letter of the text geometry is given its own axis and offset (to separate the letters). Each letter is now its own independent geometric object. Words are also given their own axis.
