Neopixel stair light project

Hi.

I turn to the forum for som guideance and some help.
I have a staircase with 14 steps wich i want to light up with my neopixels.
Some how i have an idea on how to do it but i see that my code is going to be messy and long.
I have searched and searched the internet for clues but i am stuck on how to simplify the code.
Since the steps dont have equal amount of leds i decided to make the code with 14 different strips.
Maybe stuipd.

I`m going to use and proximity sensor in the bottom and the top wich has adjustable range.
The sensor works fine.

The resault im looking for is to light the 2 first and 2 last leds on each step with a dim color as a standby light.

When a sensor is activated i want each strip to light up with all leds step by step with a delay of aprox 1 sec between each step.
follow by turning of the light behind after aprox 5 -10 sec.

I have added the code i have so fare with only to strips set up. It works fine but i guess as anyone with programing knowledge can see this is going to be a very long code when i add in all the 14 strips in the code.

I will be very happy if anyone could guide me in a better direction.
So that i maybe only needed 1 void for colorwipe up and 1 for down but a way to indexing the stips.

And if someone have an idea of how to tell the stip to light specific leds in a strip.
Example. strip 1 have 22 leds. you want with 1 line light up led number 0,1,20 and 21. How to??

Thanks a lot for any suggestions.
Sorry for any bad english.

Code below:

#include <Adafruit_NeoPixel.h>

Adafruit_NeoPixel strip1 = Adafruit_NeoPixel(22, 6, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip2 = Adafruit_NeoPixel(20, 7, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip3 = Adafruit_NeoPixel(20, 26, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip4 = Adafruit_NeoPixel(20, 27, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip5 = Adafruit_NeoPixel(20, 28, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip6 = Adafruit_NeoPixel(20, 29, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip7 = Adafruit_NeoPixel(20, 30, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip8 = Adafruit_NeoPixel(20, 31, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip9 = Adafruit_NeoPixel(20, 32, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip10 = Adafruit_NeoPixel(20, 33, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip11 = Adafruit_NeoPixel(20, 34, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip12 = Adafruit_NeoPixel(20, 35, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip13 = Adafruit_NeoPixel(20, 36, NEO_GRB + NEO_KHZ800);
Adafruit_NeoPixel strip14 = Adafruit_NeoPixel(20, 37, NEO_GRB + NEO_KHZ800);
