Currently no. Usability practices tell me the less a user has to interact and choose what to do the more effective the system will be overall if small nuances can be handled programatically. I didn't want a bunch of options, as you can probably tell lol.
What I was looking for however is something from Facebook saying specifically how long a description can be before it's shut off... But I can't find that anywhere.
For you however, you're in luck... for the description, my plugin first checks for a post excerpt (which you could type your 200 there) before it goes to auto-generating the desc. So use that?
If this is for your author pages again then until I can get all that added in... wing it! :)
