Label always above link

Hi,
is there a way to have a label to be always above a link, even if the link goes from right to left?
E.g. see this example: https://gojs.net/latest/intro/linkLabels.html#LinkLabelSegmentOrientation
Can the “left” label be always on top and upright even if the link goes from right to left (e.g. if “Beta” node is moved to the left side of the “Alpha” node)?

Would this meet your needs?

      $(go.Link,
        $(go.Shape),
        $(go.Shape, { toArrow: "OpenTriangle" }),
        $(go.TextBlock, "LABEL", { alignmentFocus: new go.Spot(0.5, 0, 0, 16) })
      )

Feel free to adjust the alignmentFocus spot to suit your needs.
