I haven't found any discussion about this. We all know that epic and above items like to have their names. They are kind of special after all.

I can't imagine myself at the very end wearing let's say Voidstone Greatsword of Flame that will be legendary tier. I want to name it, lets say as Hand of Talos, or differently and then wear it proudly or sell it away for lots of gold coins. Even if naming our creation would require a perk that we could unlock at lvl 50 of crafting profession it still would be geat - even greater.
