Via Excel VBA, opening Word Document to Complete Mail-merge. Is there way to Automatically set Word Doc Source equal to Excel Spreadsheet?

Question

Have the below Excel VBA Code:

1. Creates Word Object since I want to link my spreadsheet to a Word Mailmerge template
2. Asks the user to specify the Word Template
3. Opens the Word Template (to which later code not displayed merges the data with the template)

Challenge: if the Word Template is already "sourced" to a different spreadsheet (say the spreadsheet from last month which has a different name), the user has to go through the steps to select the "newer" spreadsheet which I am calling the Word Template from.

Question: is there a way within the Excel VBA (or other) to open the word doc so that the source is changed to the current spreadsheet?

Set wd = GetObject(, "Word.Application")
If wd Is Nothing Then
    Set wd = CreateObject("Word.Application")
End If

Dim Letter_File As FileDialog
Set Letter_File = Application.FileDialog(msoFileDialogFilePicker)
With Letter_File
    .Filters.Clear
    .AllowMultiSelect = False
    .InitialFileName = "\\Nasprod-5\gbop\Customer Service\RMDs\Process Improvements\"
    If .Show = -1 Then
        Fileaddress = .SelectedItems(1)
    Else
        Exit Sub
    End If
End With

If MsgBox(Fileaddress, vbOKCancel) = vbCancel Then
    MsgBox ("Canceled")
    Exit Sub
End If

Set wdocSource = wd.Documents.Open(Fileaddress)

The following is code I use in Word vba.

Dim strFileName As String
strFileName = WorkGroupPath & "Parts\Merge Data\Clients_Merge.xlsm"
'
'   Attach Merge list
With ActiveDocument.MailMerge
    .MainDocumentType = wdFormLetters
    .OpenDataSource Name:=strFileName, _
                    SQLStatement:="SELECT * FROM `Clients$`"    ', _
                                                                '
    '       Show merge data
    .ViewMailMergeFieldCodes = False
End With

'   Find client
Application.Dialogs(wdDialogMailMergeFindRecipient).Show

This is run upon opening/creating the primary merge document. You could assign the long name of your data source to strFilename.

You might have to change the With to:

With wd.ActiveDocument.MailMerge

The following came from recording a MailMerge in Word.

    .OpenDataSource Name:=strFileName, _
                    SQLStatement:="SELECT * FROM `Clients$`"    ', _
