Wish there was a way: to sort the open conversation tabs

Tabbed conversations are great, especially for folks that have more than a handful of chats going on at the same time, however I wish there was a way to sort them alphabetically, so it's easy to find your contacts.

Even the popup window when you hover on the Lync/SfB program on your task bar seems to order the list by placing the most recent new IM session at the top, but as you see in the  screenshot below, the tow lists don't exactly match up either.

Skype for Business client - Tabbed conversations.
Conversation window in the background, and the taskbar list when you hover on the client, in the foreground.

If anybody has found a way to sort either of these lists, please let me know :-)
