Possibility to add Europe 868 alt preset?

[tronba]

In Norway, around half of Meshtastic users have moved from standard LongFast to 869,618 MHz, with BW:62,5kHz SF:8 CR:5.
This is to avoid smart meters that flood the standard frequency, especially in big cities.
As I understand it, this is also the case in some other European countries.
Would it be a good idea to add a preset for this under "Europe 868"?
(I know calling it "LongFast Alternate" might not be technically right, because it's closer to a narrow configuration, but the usecase is as a direct alternative to the default preset.)

We have been made aware of meshtastic/firmware#7481 which appears to be exactly what we need. Exciting 😁
