For years this has been suggested and the answer is no, SBD was created to be sort off pegged currency so that businesses created in Steem can have a sort-off stabled currency to work with but right now its not the case!

And be prepared for a lot more complexity when SMTs come out because these tokens will work like Steem and you'll be able to power up/power down/delegate these as well and there's gonna be hundreds of them!
