A quick workaround to move all uSync macro keys from a node to an attribute (see https://github.com/KevinJump/uSync/issues/231) - just place in the uSync\data\macro folder and run

USyncMacroAddKeyAttr.ps1

# Get all .config files in the current folder
Get-ChildItem "./" -Filter *.config | 
Foreach-Object {
    [xml]$xml = Get-Content $_.FullName
    
    # Add Key attribute
    $macroNode = $xml.SelectSingleNode("macro")
    $macroNode.SetAttribute("Key", $xml.macro.Key)
    
    # Remove Key node
    $keyNode = $xml.SelectSingleNode("macro/Key")
    $macroNode.RemoveChild($keyNode)
    
    $xml.Save($_.FullName)
}
