It's currently not possible to have subcommands formatted in groups, e.g. instead of:

subcommands:
  {a,b,c,d,e}
    a          a subcommand help
    b          b subcommand help
    c          c subcommand help
    d          d subcommand help
    e          e subcommand help 

you should be able to get something like:

subcommands:
  group1:
    a          a subcommand help
    b          b subcommand help
    c          c subcommand help
  group2:
    d          d subcommand help
    e          e subcommand help
