((Maybe Tori is referring to an adverbial usage of 改め,
Btw sorry for the previous answer, I misunderstood it.
I mean, instead of 改め直す、as a compound verb in the sense of 再度ものを正す. It seems more likely an usage of 改めて、直すこと. *改めて has its own dictionary entry.
Checking the provided explanation from dict.goo, within the former words(修正 and 改正) ,
改正's explanation kind of examples it:
「改定」は、一度決めたことを定め直すときに使う -> 一度決めたことを 改めて 定める* 時に使う
