Is there a way to slow down servo movement speed?

Question

Despite searching I was not able to find an answer to this question. I have a servo attached to a pin that moves an arm back and forth. The problem is that it moves too quickly. Is there a way within pigpio or some other method to slow down the movement?

(There was an answer posted ~3 years ago that basically said it can't be done here. I was hoping things have advanced since then.)

This is some sample python code that reproduces the problem. Servo is connected to pin 4.

import time
import pigpio
pi = pigpio.pi()

pi.set_servo_pulsewidth(4, 1500)
time.sleep(0.4)
pi.set_servo_pulsewidth(4, 500)

Thanks!

This may work as an example, give it a start and end position, and the time(seconds) you want it to take to move there. It will break the movement up into 100 incremental moves this will slow down the movement

func moveServo(start,end,delta):  #move from start to end, using delta number of seconds
     incMove=(end-start)/100.0
     incTime=delta/100.0
     for x in range(100):
          pi.set_servo_pulsewidth(4, int(start+x*incMove))
          time.sleep(incTime)
