Be able to close a line into a polygon

[GregMillsFreesat]

Hi,

If I draw a line that has a start and end-point at the same position, I would like Draw.io to convert that line into a polygon (with an optional fill, etc.)

Once that polygon has been created, I would like to still be able to modify that polygon using the same node-point modifiers that were available when it was a line.

This would allow the creation of basic custom shapes (polygons).

Here's a step-by-step summary of how I would see the user making use of it.

I would appreciate it if anyone could share a hack for getting this to work. I am willing to help with the implementation; I just don't know how to enter the definition of the shape (beyond defining some JSON parameters for their styles).

A hack I've considered is to use the Polygon class and add nodes via the Edit Style button, but it doesn't work for curved lines.

verticalLabelPosition=bottom;verticalAlign=top;html=1;shape=mxgraph.basic.polygon;polyCoords=[[0.95,0.9],[0.95,0],[1,0],[1,0.9],[0.95,1],[0.05,1],[0,0.9],[0,0],[0.05,0],[0.05,0.9]];polyline=0;fillColor=#999999;strokeWidth=2;

You can paste the style above to obtain this shape :
