Change Binding format to another format in existing diagram

For existing diagram for some of the nodes have location binding format like:

                       new go.Binding("location", "loc").makeTwoWay() // 

so in diagram json it binded as {…, “loc”:{“class”: “go.Point”,“x”: 624,“y”: 529},…}

I have larges diagrams and now I have need to change this to below format without affecting the existing diagrams.

     new go.Binding("location", "loc", go.Point.parse).makeTwoWay(go.Point.stringify)

Is that possible convert the existing diagram json binding properties

"loc":{“class”: “go.Point”,“x”: 624,“y”: 529} to “loc”:"624 529"

You’ll need to replace the conversion function with one that checks its argument to see if it’s a Point or a string. If it’s a Point, return it, otherwise parse the string using Point.parse.
