I could not find a way to filter bounty questions by tag (e.g., Excel)

Is that possible at all?

**EDIT** ("research" inspired by answers)

Answers below explained why I was not seeing a *featured* tab for tag *excel*.

The way to arrive at an explicit message stating that there are no featured questions with a given tag is by first clicking on the *featured* tab, and then searching for the tag in the top right search field (*excel* in this case).
