I misunderstood you. Yes, if the marker is inside of the region this works as intended. However, if there are many subsequent regions after said marker, they will be labelled the same as the marker ahead of them. Image to illustrate:

This may be working as intended, but it doesn't feel overly intuitive to me at least

. A fix would be great for my workflow - hopefully others benefit also.
