Improving the properties of the control measure symbols (area)
The properties of the symbols for control measure symbols for area objects should be improved, since not all amplifiers can be filled in according to 2525c or 2525d:

Proposal for the content and structure of the property window (named "CM - Area") for control measure area symbols:

Remarks:
The green marked amplifiers correspond to the specifications according to 2525d.
The amplifier "Hostile (Enemy)" is not necessary in my opinion, because "Hostile" can be defined by the standard identity.
The symbol icon (field "A") is already defined when the basic symbol is selected.
The Icon "Change Symbol Type" is used to change the "basic symbol" within the control measure point symbols without the user having to create a new symbol and thus discard the previous entries.
