Merging documents behavior

This is such a simple question, I’m sure I’m doing something wrong.

I remember I used to select items in my database and then right-click merge, and a new merged document was created. At that point, the old unmerged documents were still selected so I could press delete and they’d be removed.

However at some point that behavior seemed to change. Now the newly merged document is selected. I have to search through my inbox to locate the unmerged documents to select them and delete them.

Is there any way to automatically delete the original unmerged documents after a merge, or to set it up to keep the unmerged documents selected after a merge to make it easy to delete them?
