Choosing a selection of benchmarks in a hierarchy

When I create a job, and select to "choose" solvers/configurations and "choose" also a benchmark selection, the documentation (on the site itself during job config) seems to suggest that I'll be able to choose benchmarks from the entire space hierarchy. But after selecting my solvers, I'm presented with no options for selecting benchmarks (because all benchmarks are in subspaces). Clearly the selection is only supported for benchmarks in the space (not in its subspaces).
