Power Query Accumulate with text in list

Hi Dicken 

Is it possible that text values can be anywhere in the list, and should all be ignored for the cumulative sum?

e.g.

This:

{"A", 2, 3, "B", 4, 3, 2, 3, "C", 2}

becomes this:

{"A", 2, 5, "B", 9, 12, 14, 17, "C", 19}

Here is an example of how I might handle this more general case (as well as your original example):

let
  alist = {"A", 2, 3, "B", 4, 3, 2, 3, "C", 2},
  CumulativeList = List.Generate(
    () => [
      Index          = 0,
      Value          = alist{0},
      IsNumber       = Value.Is(Value, type nullable number),
      NumericalValue = if IsNumber then Value else 0,
      CumulativeSum  = NumericalValue,
      DisplayValue   = if IsNumber then CumulativeSum else Value
    ],
    each [Index] < List.Count(alist),
    each [
      Index          = [Index] + 1,
      Value          = alist{Index},
      IsNumber       = Value.Is(Value, type nullable number),
      NumericalValue = if IsNumber then Value else 0,
      CumulativeSum  = [CumulativeSum] + NumericalValue,
      DisplayValue   = if IsNumber then CumulativeSum else Value
    ],
    each [DisplayValue]
  )
in
  CumulativeList
