You will need to install a user script manager extension to install this script.
This is an authorized fork of gertbroos' / houseofdreams "WME LevelReset" (https://greasyfork.org/en/scripts/14414-wme-levelreset), adding the ability to change target lock values for the various road types on the fly. This is useful in the USA as lock standards vary from State to State.
You can now save your custom lock levels so they don't reset on a browser reload.
Future functionality will include State-based default lock levels, since each community has their own locking standards.
Known issues: Sometimes after moving your visible area and pressing a relock button, the segment count doesn't zero out, even though the pending edits are properly in place to be saved. This is a cosmetic issue.
