Ask HN: Doodle Poll Filler Outer?

I am a newb about this: is there a way to point a doodle poll that someone has sent me to my calendar, and have the doodle poll automagically filled out based on my calendar availability (and perhaps based on some simple rules e.g. start of day and end of day)? Ideally without having to hand over the contents of my calendar appointments to doodle dot com? (availability fine, but contents, no)? Is this part of what you get when you pay for a doodle account? Is there a way to get this done? Doodle polls are killing me.
