### Description
- [x] Here are some details about my PR, including screenshots of any UI
changes:
DAG subcommands are now nested inside the main command. However, the
subcommand dictionary contained only the main commands. This resulted in a
KeyError when querying for a subcommand from the dict.

this extremely good reason:
Tests already exist.
