Is --subproblem parameter really needed?

[buus2]

Each single step in whales constantly belongs to exactly one sub problem. So why should user care about sub problem by typing --sub_problem sth in command line? I think the sub problem could be inferred from the task automatically, eventually user could have a possibility (not an obligation) to choose one in dry dun mode.
