Style folder name in Bold if there's unread mail

In Outlook 2010 folder names were bold if there was unread mail in them. In Outlook 2013 this was changed, and by default there's only a bold-blueish number behind the folder.

How can I once again have bold folder names for folders with unread mail in Outlook 2013?

Things I've tried, to no avail:

• Search the web. I even landed at our friends at experts-exchange (scroll down to see the "answers" ;-))
• Conditional formatting tips on the web, but they all come down to changing other UI bits
• Custom conditional formatting rules, but they all seem to be about the list of messages (middle pane), not about the list of folders

A Microsoft MVP mentioned on answers.microsoft.com that it's just not possible. That post was from quite a while ago, I would hope that someone has found a solution or workaround by now?

To clarify, here's a screenshot with indication of what I'd like:

The answer on microsoft.com you've found is correct: this can't be done in Outlook 2013.
