So the problem here is that there are 3 types on annotation (Mark, Point and Area)
The Mark one is the only type (I think, I've not used annotations much) that can be linked to the Status dimension (or ATTR), and this changes as the mark is the combination of dimensions Status/Shapeid/Point. so if any of these 3 change it is not longer linked.
If you are not so concerned with the label being exactly in the middle! you could use a real label like so
and then Dual-Axis (sync axis and make the transparency for the circle mark 0%)
Hope that helps
