Snapping an arrow to anchor points on the bottom or sides of a UML diagram

[mihaiconstantin]

I am trying to snap an arrow to the anchor points of a UML diagram (e.g., 25% or 75%). I can do this at the top of the diagram, but not at the bottom (i.e., please see the recording below).

I believe the issue is that the method rectangles take precedence over the encompassing class rectangle. I think this issue also occurs when trying to snap to the sides of the class diagram.

I've been struggling with this for a long time and would appreciate any input you could share. Do you have any ideas on how I can snap my arrow to those anchor points at the bottom or sides of the diagram? I am aware that I can use the alt key to manually position the arrow, but I would prefer to snap at those predefined points.

Thanks a lot!

One solution I found is to (1) untick the "Connectable" property for the methodTwo rectangle, (2) connect the arrow at the now-visible desired anchor point, and (3) undo the first step. I am curious if there is a better way to do this.
