Anchor label for connectors (from decision element

[SilverFox]

I am used to the style of having the 'yes/no' label of connectors from a 'decision' symbol (activity diagram) be placed at the source rather than the target end. When analyzing complex diagrams with long paths, it makes it much easier to see which path you're following. EA places the 'yes/no' label at the target end of the connector. I can move it back to the source end, but then if I move the target element, the label moves around unpredictably, and can get lost. Is there a feature to 'anchor' the label at a particular end? If so, can such a feature be provided?
