Feature request, Ship card sender Class B.

[Gazman429]

Is it possible to add the type of Class B unit on the ship card sender, Message 18 - Parameter Class B unit flag, sender could display Class B+ (as it often seems to get referred to) for Class B/SO (SO-TDMA) and Class B for B/CS CS-TDMA, some might find it helpful when trying to perfect their station coverage and why some Class B vessels drop out at short ranges and others don't as there is two different power transmit levels for the class, 5 watts B/SO & 2 watts B/CS, just an idea.
