Feature request: support for different journal files

Feature request
It would be nice if journal-brief had an option to select which journal files to process.

Why?
I use systemd's systemd-journal-remote.service and systemd-journal-upload.service to collect log entries from different machines on a single server. So next to the usual journal files in /var/log/journal/UUID/*.journal, I got other journal files in /var/log/journal/remote/*.journal.
