Is there a way to define your own script such that the "switch" variable recognizes it?

So essentially what I'm trying to do is add a quadruple exponential moving average to this code:

Code:
# Heikin Ashi Smoothed
# HoboTheClown / blt
# 9.15.2016

# HoboTheClown: I recently found a code for smoothed heiken ashi bars,
# however for some reason all the bars are displayed as one color (going up or down).
#
# blt: Modified the code and replaced the addchart code at the bottom,
# you should now see proper coloring. This is how that was coded to plot
# as an overlay to the chart candlesticks. That is two sets of candles,
# with different coloring for each. If you have the heikin ashi candle
# coloring code on your chart, then they will likely appear the same color.

#Update that "fixes" the green candles.

I got this study here if anyone's curious: https://usethinkscript.com/threads/smoothed-heikin-ashi-for-thinkorswim.216/page-2

Anyway, my issue is I'm trying to add a QEMA, which is currently not built into TOS. I made my own code for my QEMA based on the code for the TEMA:
Code:
input price = close;
input length = 10;

def ema1 = ExpAverage(price, length);
def ema2 = ExpAverage(ema1, length);
def ema3 = ExpAverage(ema2, length);
def ema4 = ExpAverage (ema3, length);

plot QEMA = 4 * ema1 - 4 * ema2 + ema3;
QEMA.SetDefaultColor(GetColor(0));


My question is, is there some way to get switch(movingAverageType) to recognize a custom script or is that purely for built-in indicators? I had a look at the manual and they said to use the "script" function to be able to reference your own scripts in a piece of code. I tried that but no luck. Any help would be appreciated.

Thanks a lot dude. I asked Mobius this question a few hours ago and he just responded, he told me my QEMA formula was wrong and I should use this instead:

Code:
input length = 10;
plot QuadEMA = ExpAverage(ExpAverage(ExpAverage(ExpAverage(close, 10), 10), 10), 10);

I went ahead and did that and it works. Thanks again!

I edited the script I posted above with the new formula. Thanks for letting me know. Glad it works for you!

Thanks for your help man. Just one more thing I'd like to add to this if it's possible, do you think one can add a case for regular heikin ashi candles? This script is for a double-smoothed heikin ashi but it'd be useful to also have the ability to use just a regular heikin ashi, that way I can have both candlesticks and heikins on my chart.
