Run a macro when a change occurs in a range of cells (two macros and two cell ranges)

I'm using this code to run a macro whenever data is entered/removed from a cell within a range.

Private Sub Worksheet_Change(ByVal Target As Range)

Dim KeyCells As Range

Set KeyCells = Range("M3:M52")

If Not Application.Intersect(KeyCells, Range(Target.Address)) _
    Is Nothing Then
    
Call FormatChart

End If
End Sub

Now I need to do the same thing for a different cell range (E3:E52) and a different macro (FormatChart2). Do I need to make a new Private sub or can I add it into the existing code?

Replace this....

Private Sub Worksheet_Change(ByVal Target As Range)
Dim KeyCells As Range

Set KeyCells = Range("M3:M52")

If Not Application.Intersect(KeyCells, Range(Target.Address)) Is Nothing Then
    Call FormatChart
End If

Set KeyCells = Range("E3:E52")

If Not Application.Intersect(KeyCells, Range(Target.Address)) Is Nothing Then
    Call FormatChart2
End If

End Sub
