Want a soft and smooth braking, need help

I have a big problem when it comes to brek my E-Maxx, the 2200KV makes a hard full stop and not a smooth and soft braking as I like to have it.

Could you please help me to dial in the right setup for me in the Castle Link software.

I would like to have it controled by using the throttle, to affect how sharp deceleration I want. A smal puch on the throttle equal to soft breking, and full puch on the throttle equal to full hard breking.
