Legendary Mount Scrolls

I know there is already a topic that touched on this, but the thread is a couple of months old, so I didn't want to necro it.

I was just wondering if there is a way yet, to turn legendary pets into mounts. I realize most people also want them added to their bestiary, but for me atm, I'm not too concerned with that. I'd just like to be able to make a legendary pet( which was originally a mount) into a mount...if it's any way possible.

Thanks
