This sounds like an entpreneurial idea to offer a service if this is in demand. This type of accounting system could be a service provided by some 3rd party entity, since the blockchain is public.

I don't feel steemit should offer it. I think it is a completely separate animal that needs its own website.

The equivalent of what you've asked, is like asking craigslist when you use their system. They don't offer that..

Perhaps wherever you are exchanging your STEEM could also be a place where this accounting occurs. Not from steem itself.
