The same is not possible when using the `with_annotated` decorator.\n\n## Possible design for a solution\n\nEither allow custom types (as `Typer` does — see [custom types](https://typer.tiangolo.com/tutorial/parameter-types/custom-types/)) and make a best-effort type conversion for arbitrary annotations, or add an additional parameter to `Option` and `Argument` (for example `conversion`) that enables a two-step type conversion approach.","author":{"url":"https://github.com/neoniobium","@type":"Person","name":"neoniobium"},"datePublished":"2026-06-10T14:40:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1688/cmd2/issues/1688"}
