Global N2K display dimming

[Ron Micjan]

Does NMEA 2000 have a PGN for global dimming? It would be super nice to tell one device to dim the display to say 20% and have the rest follow suit. When you have 11 displays to dim in the pilothouse when it's getting dark outside, a single control would be useful. call me lazy

NMEA has no set PGN established for this, but some have done this type of thing with Proprietary PGNs. I would be good if there was a standard by NMEA so all the companies could do something like that regardless of brand.
