Copy blacklisted battletag.

[hasnogaems]

There is a trick how to get battletag of the player with whom you played. You need to blacklist him, and then in wow you can see his btag. But i have huge problem with people whose btags use non english but lookalike letters. The easiest way is to copy btag directly from blacklist but with defaut interface i can't.
Is there any addon that can allow me to copy names from blacklist?
