how to assignee a issue to validator in post-function

[Nic Brough [Adaptavist]]

I'm sorry, that does not make any sense in English and it mixes up too many concepts and words for me to begin to guess what you might mean by it.

The best guess I have is that you want to change the assignee of an issue in a post-function, but you have added the word "validator" in the middle of your list of words and that makes me doubt the guess.

Could you explain what you are looking for in a different sentence?
