Not possible, I think. How would Timeline/Scrivener know where to put that information? You could probably get some of the data across using custom meta-data fields.
How much information do you think you need to carry over from your character profile to the timeline? The problem is that no two authors are likely to use the same format for characters and even the same author will likely have a different format for long-form novels vs short stories. One project may have character profiles that are one paragraph long and the next project may have 20-page profiles. Even within the same project, you likely have reams of information about your main characters but much less about incidental people that wander through your plot. Nor does Scrivener store this information in any standardised format which AT2 could consume. The character documents are just flat rich-text files. For that matter, so are the documents we are synchronising to events. Custom metadata may be a partial solution, but there are limited ways to display or do anything meaningful with that information in Scrivener. Using the document synopsis and happing it to the notes field for entities might be a way to compromise and allow you to at least carry over a few key pieces of information that would be important while building or displaying a project timeline. You might want to weigh in on [this thread](https://www.aeontimeline.com/forum/channel/#!/wish-list:smarter-entity-synchronizat) and let Matt know what you specifically want to see in the way of entity synchronisation for characters, events, arcs or any other entity type you might see fit to create in the future.
@Craig, I was hoping it would be done similar similar to the way events are mapped i.e. on name and if it didn't find it you could map it manually. Yea, I've copied some info over using the meta fields - Thanks for replying, @razyr, Understand what you're saying about character format and length of profile but was hoping it would at least map to a text file, or be able to associate it with a file in Scrivener but fair point, I see the complication. Thanks for your comprehensive feedback, I'll checkout the thread mentioned.
