One manpage per subcommand output

Is it possible to output multiple manpages/html pages eg for commands with multiple subcommands and a lot of options? I'd like to have the main command in a page and each subcommand in a separate page.

I try as follows but don't get the expected results.

Main command rst file - I try to remove all subcommands in the output my setting maxdepth: 0 but it does not work. Still all subcommands are included in the disco section:

.. autoprogram:: discodos.cmd.cli:ArgParse.parser
    :prog: disco
    :maxdepth: 0
    :groups:

one of the subcommand rst files - works as expected, only the disco searchcommand is shown:

.. autoprogram:: discodos.cmd.cli:ArgParse.parser
    :prog: disco
    :start_command: search
    :maxdepth: 1
    :groups

I have some index rst files too and in html output what I am trying to achieve looks quite good already, except the main command issue. These are the index files:

DiscoDOS manual
***************

.. toctree::
    :maxdepth: 2

    index_commands_reference

Commands reference
******************

.. toctree::
    :maxdepth: 1

    disco
    disco_search
    disco_mix
    disco_suggest
    disco_import
    disco_setup

In manpage output I still get one big manpage, containing all subcommands. How can I control that pages should be separated?

Start with the autoprogram entry point discodos.cmd.cli:ArgParse.parser and the disco, disco_search, disco_mix, disco_suggest, disco_import, and disco_setup RST files. Build the documentation in both HTML and manpage formats and compare how :maxdepth: and :start_command: affect the generated pages. Done means the main command and each subcommand are emitted as separate pages in manpage output, matching the existing HTML structure.
