Is it possible to combine these into one Macro

The 1st sub acts on columns by a array of header names


I have to run the 2nd sub on numerous non-contiguous columns so I am calling it up the 10 different times.


I would like to combine the first sub with the second so as to run the 2nd sub by a list of header names.


I have tried combing them but have had no success, can't get how to use the"colToFormat" of the 1st sub in the 2nd sub.


Thanks

Code:

Sub fmt()
    ColList = "Field1,Field2,Field3,Field4"
    colarray = Split(ColList, ",")
    Set colToFormat = Nothing
    For Each heading In colarray
    Set headingFound = Range("A:A").Offset(0, ActiveSheet.Cells.Find(What:=heading, After:=ActiveCell, LookIn:=xlFormulas, _
        LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
        MatchCase:=False).Column - 2)


      If colToFormat Is Nothing Then Set colToFormat = headingFound Else Set colToFormat = Union(colToFormat, headingFound)
    Next
    MsgBox colToFormat.Address


End Sub
