There are all sorts of modifications that people might want to make to posts before they're imported/created, and it's a losing battle to try to provide actual options for all of them. The easiest approach is probably to just add the ability to filter posts right before they're imported. We've already got an action that fires after each post is imported, allowing developers to do more customized things.
It looks like filtering $this->posts right before this line would give pretty good control over things.
