Can we use the WordPress import function to import into Custom Post Types in Squarespace?

Hello there!  I've been working on doing a migration of several years worth of content into a squarespace blog, and have pretty much figured out how to do a really simple import.  That said, I'm wondering if there is any way to import blog posts into a custom content type in Squarespace?  I've dug through the documentation and can't find any references to this.

Thanks!
