Adding journalctl Log sources to Webmin System Log Viewer through the gui

Hello,
After Virtualmin installation by the script, on a freshly installed Debian 12 system, Webmin System Log Viewer displays 7 “journalctl like” Log destinations (such as "Output from journalctl --lines 100 -x "). It would be nice to have the ability to add new ones through the gui (for instance, “journalctl -u postfix@-.service”).
Thanks
