Underwing registration numbers and more

I’m wishing for some enhancements for aircraft registration number handling.
Pertains to the KA350i and C208 - others probably too.
As a livery re-painter I can’t currently put an underwing reg number on aircraft repaints that don’t have that built in, due to the one wing texture being reflected for the 2nd wing. Many (RL) aircraft have reg under left wing, many countries require it.
A quick fix would be repeat the reg number display object under the left wing and have (add) a aircraft.cfg item;
atc_id_enable_underwing = 1 ; 0 disable / enable underwing number.
So that would be independent of the main reg enable/disable.

Best fix of all would be to have textures for both wings not just one, and in the case of the KA350i both engines too.

While we’re at it fix that atc_id_enable item soonist so that it works and I don’t have to use a panel.cfg hack to get rid of the main fuse reg numbers. Very very few aircraft I’ve repainted have their reg number in the ‘standard’ place and often use a custom airline or other specific font.

So some of the atc_id_? items I’d like to see for reg number handling might be;
atc_id = “N-REGX” ; tail number (as it exists now - but see below)
atc_id_enable = 0 ; enable tail number (but functioning it doesn’t currently)
atc_id_enable_underwing = 1/0 (new item on/off underwing reg)
atc_id_enable_placard = 1/0 (new item on/off cockpit placard reg)
These would give us independant control of native reg number display.

Related is the issue of “I have to enter reg number every time I set up a flight” (if the atc_id is “”)
If the user changes or enters a reg number while setting up a flight they could be presented with a “Do you want to save this Registration Number to the aircraft.cfg file ?” dialog. MFS could then write that (or not) to the aircraft.cfg and it’s going to stick solving the ‘reg number every time’ gripe, and (bonus) the user does not have to edit aircraft.cfg themselves.
