Plane. Settings to make plane lose height aggressively

Hello all,
my current goal is to set up a plane so it can lose height aggressively when the next waypoint is below the current height.

With the current settings, the plane tries to maintain target airspeed even in the case described above.
I’ve found parameter TECS_SPDWEIGHT which I think, I can modify in flight to get the behavior I want.
But this requires code modification.

Is there any way to achieve the next behavior by changing parameters only (and what parameters it should be?)
If a plane requires to gain height it maintains the airspeed setpoint
If a plane flies horizontally it maintains the airspeed setpoint
If a plane has to lose height: it can omit the airspeed setpoint, while staying in a range of ARSPD_FBW_MIN…ARSPD_FBW_MAX

I would try commanding increased speed for descent. This should help as TECS will be able to maintain higher speed. Be careful with MAX speed as it can cause aircraft to be unable to maintain desired altitude if speed not possible in level flight is set.

The best option would be to have and enable reverse thrust as this would allow for much steeper descent without overspeeding.
