When will I be able to import feature-length screenplays from FD or MM w/o MAJOR formatting problems

It doesn't matter what I try to import (txt, fdx, mmsw, etc.), the formatting is very messed up when it comes into Story.

Half slug lines / scene headings, half names, or it will import as ALL action, etc.  What's your timeline on having this fixed? I can't update other screenplays I've written without this working properly. Thanks.
