Decorate edges with counts

Is there a way to count the number of times an edge has been traversed in the graph view drawn from traces and display this info beside the edge.

I know it is possible to show the number of times a particular block has been executed. However, it’ll be quite useful to show what’s described above, just to see what the program has been up to most of the time.

Alas, currently it is not possible to add custom labels to the graph’s edges.
