Sadly, no. We don't have any built-in support for historical support  
at this time, although we have thought for a long time that this  
would be a great feature to have.

You can, of course, do it yourself manually with a bunch of  
persistent Date fields, but I agree that this is pretty cumbersome to  
have to manage yourself.
