[graph-tool] shortest path with distance in a weighted graph

Hello, To find the shortest path and its corresponding distance from a list of sources to a target in a weight graph, I did: loop over all sources: (1) run shortest_path(source, target) (2) sum up edge weights in elist Is there a quicker way to do this? Since shortest_path() finds the shortest path, I thought it should report the shortest distance as well...
