Additional marks for equipment/lines
It is possible to specify additional labels/properties/layers for equipment, lines, communications installations, couplings, buildings and other objects.
The list of labels can be arbitrary. Visually, (in some cases - such as communication lines) labels may differ in colour and line type.
Using the specified labels in the list of equipment or communication nodes/lines, etc., you can filter objects.
It is also allowed to display individual (or all) layers with selected labels on coverage maps.
Starting from version 3.18:
User marks are merged with common marks for other objects
Added the ability to customise the colour of the mark text in marks by object.
