Below are names in each cell

Column
A b c d e
Row 5 Sheet1 Sheet6 Sheet11 Sheet16 Sheet21
6 Sheet2 Sheet7 Sheet12 Sheet17 Sheet22
7 Sheet3 Sheet8 Sheet13 Sheet18 Sheet23
8 Sheet4 Sheet9 Sheet14 Sheet19 Sheet24
9 Sheet5 Sheet15 Sheet20 Sheet25

Sheet, tab, and CommandButton names are referenced by these cells name
above, meaning if I change a name in any cell above it will change the sheet,
tab and command button names referenced to the cell. E.G. A9 =sheet5, so
CommandButton1 name = Sheet5, tab name = Sheet5 and in Sheet5, A1 = Sheet5

What I would like to do is:
As each name in the cells above is referenced to a sheet and a
Commandbutton, I would now like to be able to have the cells name above also
change the codes Go To Worksheets, ("Index") to ("Sheet1") in the command
buttons Go To Worksheets code below.
Can this be done?

Code for CommandButton to Go To sheet

Private Sub CommandButton1_Click()
Worksheets("Index").Select
Application.GoTo Worksheets("Index").Range("A1"), Scroll:=True 'or false??
End Sub

Code to Change CommandButton Name

Private Sub Worksheet_Change(ByVal Target As Range)

Dim myRngToCheck As Range
Set myRngToCheck = Me.Range("a5,a6 ")

If Target.Cells.Count 1 Then
Exit Sub 'one cell at a time
End If

If Intersect(Target, myRngToCheck) Is Nothing Then
Exit Sub
End If

Select Case Target.Address(0, 0)
'use uppercase addresses here and match the addresses above!

Case Is = "A5"
Worksheets("Index").CommandButton1.Caption _
= Format(Target.Value, "mmmm dd, yyyy")

Case Is = "A6"
Worksheets("Sheet2").CommandButton1.Caption _
= Format(Target.Value, "mmmm dd, yyyy")
