[wix-users] CopyFile add Date to DestinationName

[Brian Enderle]

I am making a backup of a file when upgrading a product:

    <DirectoryRef Id="CONFIGFOLDER">
      <Component Id="BackupConfigFile"
Guid="DD561CA8-674D-4D52-840D-26A8575A3AFC">
        <CopyFile Id="CopyConfigFile"
                  SourceDirectory="CONFIGFOLDER"
                  SourceName="config.xml"
                  DestinationDirectory="CONFIGFOLDER"
                  DestinationName="config.bak" />
      </Component>
    </DirectoryRef>


Is there a way I can add the current date (something like 20151105 or
11052015) to the DestinationName to end up file a file name like
"config_20151105.bak"
