Expire nested object

It seems that the TTL cannot be set on nested object level, will ES add
this feature in the future?
As of now, say if I want to delete blog posts(nested object of user) that
are 1 year old, do I need to read all the document out, filter out the
older posts and then write them back?
Thanks,
Chen
