Remove a Specific Transformation via IPython

I have the following IPython code to add a transformation to replace a specific value, based on user input, running on Spotfire 7.13 HF002:

from Spotfire.Dxp.Data import *
from Spotfire.Dxp.Data.Transformations import *
from System.Collections.Generic import List, Dictionary 
from Spotfire.Dxp.Data import DataTable 
from System.Collections import ArrayList

#get a handle on the datatable
tabletmp = Document.Data.Tables['MasterOverride']

#set up some cursor to get the keys
cursorKeyColumn = DataValueCursor.CreateFormatted(table.Columns["KeyColumn"])

#loop only though a specific marking
markings = Document.Data.Markings["overrideMarking"].GetSelection(tabletmp)

#create lists to store values in
markedKeyColumn = []

# Iterate through the data table rows to retrieve the marked rows
for row in tabletmp.GetRows(markings.AsIndexSet(),cursorKeyColumn):
	value = cursorKeyColumn.CurrentValue
	if value <> str.Empty:

# Get only unique values
valKeyColumn = list(set(markedKeyColumn))

#Get values from user
overrideValue = Document.Properties['OverrideValue']

dataOperation = table.GenerateSourceView().OperationsSupportingTransformations[0];
transformations = dataOperation.GetTransformations();
columnForValue = DataColumnSignature("Override Value",DataType.Real);
cursorValue = DataValueCursor.CreateFormatted(table.Columns["Override Value"])

#For every month selected
while i < len(valKeyColumn):
	#Get values to establish the key of the table
	overrideKey = valKeyColumn[i]
	#Get existing value based on this key	
	rowSelection = table.Select('KeyColumn = ' + '"' + overrideKey + '"')
	for  row in  table.GetRows(rowSelection.AsIndexSet(),cursorValue):
		rowIndex = row.Index
		currentOverrideValue = cursorValue.CurrentValue

	#Replace specific value Transformation for the Value
	row_id_col_values = [overrideKey]
	transformations.Add(ReplaceSpecificValueTransformation(columnForValue, float(currentOverrideValue), overrideValue, row_id_cols, row_id_col_values, False))



That code works fine and creates a ReplaceSpecificValueTransformation. I have the following code to remove all of these transformations which also works fine:

    from Spotfire.Dxp.Data import *
    from Spotfire.Dxp.Data.Transformations import *


    #Replace specific value Transformation
    dataOperation = table.GenerateSourceView().OperationsSupportingTransformations[0];
    transformations = dataOperation.GetTransformations();

    #clear all transformations on this dataTable if needed

I am looking for code to allow me to remove a single ReplaceSpecificValueTransformation based on some input. I have tried utilizing some code at this link with no success:

I cannot figure out how to remove a specific transformation in IPython.
