Suggestion: Plane with airspeed sensor should display error if arsp trim is less than fbw min

Hi, a couple of months ago, I had a crash while rtl due to the fact that my trim arspd cm was lower than the fbw min speed.
In the main tuning page on mission planner, i edited the fbw min speed to 14, however my trim arspd cm was set to 12 from the parameter list. Therefore while rtl, the plane aimed for a speed of 12.5 m/s and stalled. I was wondering that either the setup should display an error in this case or mission planner should have an arspd trim option next to min and max fbw speeds. Is there a reason for not implementing the above?

Apologies, the option is available in the General Tuning Tab.
