Set post parent when importing CPTs

Hi!

One site I’m working on registers a CPT named “Lot” which uses the “post_parent” field to create a n-to-1 relationship with another CPT named “Auction”, so all “Lot” CPTs are part of 1 “Auction” CPT.

Using the import tool in your plugin, I see that the only post type that supports setting the “post_parent” field is “Page”.

My question is, is there a way to set the “post_parent” in other CPTs?

Thanks in advance
