Creating a PL
For locking / unlocking requests a PL should be supplied with all involved segments. From the WME screen create a PL by adjusting the zoom level so all segments to select are visible. While using the Ctrl-key select all involved segments. Then create a PL by clicking the symbol bottom right corner of your screen. The PL is now created as URL in your browser.
The Live map has also a bottom right to create a Permalink.
