如何制作argparse子菜单？

如何解决如何制作argparse子菜单？

我只是想知道是否可以制作一个 argparse 子菜单，例如在 youtube-dl 中找到的那个：

Network Options:
    --proxy URL                      Use the specified HTTP/HTTPS/SOCKS proxy. To enable SOCKS proxy,specify a proper scheme. For example socks5://127.0.0.1:1080/. Pass in an empty string (--proxy "") for direct connection
    --socket-timeout SECONDS         Time to wait before giving up,in seconds
    --source-address IP              Client-side IP address to bind to
    -4,--force-ipv4                 Make all connections via IPv4
    -6,--force-ipv6                 Make all connections via IPv6

  Geo Restriction:
    --geo-verification-proxy URL     Use this proxy to verify the IP address for some geo-restricted sites. The default proxy specified by --proxy (or none,if the option is not present) is used for the actual downloading.
    --geo-bypass                     Bypass geographic restriction via faking X-Forwarded-For HTTP header
    --no-geo-bypass                  Do not bypass geographic restriction via faking X-Forwarded-For HTTP header
    --geo-bypass-country CODE        Force bypass geographic restriction with explicitly provided two-letter ISO 3166-2 country code
    --geo-bypass-ip-block IP_BLOCK   Force bypass geographic restriction with explicitly provided IP block in CIDR notation

这可以在python中实现吗？如果是这样怎么办？也许编写一个新的 Helpformatter 子类或类？我对类的理解充其量是可疑的，但希望我只是在文档中遗漏了一些东西，这很容易实现。
