Using parameter to dynamically call a query step - Not working

[Mr_Glister]

Hi,

is it possible to use a parameter to call a step in the query?

There is a filtering step in my query, that on a few occasions I want to disable. My idea was to create a parameter which contains the string value of one of the two previous step names, so that I can choose whether I want my query to use the filtered table, or the un-filtered one (from the step previous to the filter step). 

But I'm getting the following error: Expression.Error: We cannot convert the value "#"Filtered Rows"" to type Table.

I'm showing an example script below. 

Example:

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WciwoyElV0lEKSk1RAFKGOiZKsTrRSk6JeUAIFIhMzcnJLwcyDHTMTcFS/kWJeekgLXCGEVg8IKc0F2GQgY4RUHksAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Fruit = _t, Color = _t, Price = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Fruit", type text}, {"Color", type text}, {"Price", type number}}),
#"Sorted Rows" = Table.Sort(#"Changed Type",{{"Fruit", Order.Ascending}}),
#"Filtered Rows" = Table.SelectRows(#"Sorted Rows", each ([Color] = "Red ")),
#"Multiplied Column" = Table.TransformColumns(#"Filter OnOff", {{"Price", each _ * 1.2, type number}})
in
#"Multiplied Column"

let
    Source = Table.FromRows (
        Json.Document (
            Binary.Decompress (
                Binary.FromText (
                    "i45WciwoyElV0lEKSk1RAFKGOiZKsTrRSk6JeUAIFIhMzcnJLwcyDHTMTcFS/kWJeekgLXCGEVg8IKc0F2GQgY4RUHksAA==",
                    BinaryEncoding.Base64
                ),
                Compression.Deflate
            )
        ),
        let
            _t = ( ( type nullable text ) meta [ Serialized.Text = true ] )
        in
            type table [ Fruit = _t, Color = _t, Price = _t ]
    ),
    ChangedType = Table.TransformColumnTypes (
        Source,
        { { "Fruit", type text }, { "Color", type text }, { "Price", type number } }
    ),
    SortedRows = Table.Sort ( ChangedType, { { "Fruit", Order.Ascending } } ),
    FilteredRows = Table.SelectRows ( SortedRows, each ( [Color] = "Red " ) ),
    MultipliedColumn = Table.TransformColumns (
        if DoSomething = "FilteredRows" 
        then FilteredRows 
        else 
            if DoSomething = "SortedRows" 
            then SortedRows
            else ChangedType,
        { { "Price", each _ * 1.2, type number } }
    )
in
    MultipliedColumn

Thanks! I will accept this as a solution. 

But do you think there would be a more elegant solution? In order to do what you suggest I have to maintain the manual string of the step names in two places, both in the list of values in the parameter and then in the actual script again.
