Clr (F5) switch function also as a free selectable switch item or Lua api

I would like to get a bit more freedom about how and when to clear the flight data Clr (F5)

Today I have to press Clr (F5) to reset the flight data, there is no other way to do it.

I would like to reset the flight data via an LUA app, maybe when a fullloaded battery is connected or a delay time after landing is elapsed or ... that is a decision which has to be programmed in LUA.

To enable this functionality I can imagine two different solution:
1. Jeti provides a menu topic where the user can define a switch item which acts like the Clr (F5) button.
or
2 Jeti extends the LUA api something like <system.clrFlightData(press)>
<press> could be "short" or "long" or "super short"
"super short" will only clear the signal lost alarm

Kind regards
Andre
