replacing a sheet a sheet from another spreadsheet = updating range names

I want to completely replace a sheet in my current spreadsheet from an identically named sheet from a master spreadsheet (macro within a button).
The sheets of the target sheets contain named ranges. The sheets of the master also contain these same named ranges.

I'm using this code:

Sub TestingUpdate()
'
' TestingUpdate Macro
'

'
    Workbooks.Open Filename:= _
        "\\server1\company\Products\Lift Tables\Engineering\Lift Table configurator- Jon's project\Development\testing updating\LiftMate.xlsm"
        'LIFT TABLE DATA complete copy
    Windows("LiftMate.xlsm").Activate   'added
    Sheets("LIFT TABLE DATA").Select
    Cells.Select
    Application.CutCopyMode = False       'added
        Selection.Copy
    Windows("LiftMate-Quote.xlsm").Activate
    Sheets("LIFT TABLE DATA").Select
    Cells.Select
    ActiveSheet.Paste

End Sub

I want to copy the sheets and the named range definitions from the master into the target.
When VB does the copying the following message comes up for every named range:

"A formula or sheet you want to move or copy contains the name 'ENTTABLE', which already exists in the destination worksheet. Do you want to use this version of the name?"

I want the VB script to automaticially say "yes" to this question everytime.
