Describe the feature

Whenever you add a term to the accept.txt file of a Vocab, helpful suggested text is created for when the capitalization is incorrect.
(For example, "Use 'LaTeX' instead of 'latex'").
It would be convenient if there would also be an action defined to automatically replace the text with the correct version.
I can do this currently by defining a rule like this:

extends: substitution
message: Use '%s' instead of '%s'
swap:
  (?i)latex: LaTeX
action:
  name: replace

Would it be possible to have this action automatically defined for vocab terms?
