have km supported that feature?
Has Keyboard Maestro supported a feature that was announced yesterday?
But apparently there is scripting support and a command line tool for listing and executing Shortcuts, so it should be possible. And indeed, should be possible immediately using the Execute a Shell Script or Execute an AppleScript actions.
As macOS Monterey just has been released as a developer beta, then I think the developer has not made it yet. The more relevant question could be what support for Shortcuts would come to Keyboard Maestro. But I think @peternlewis needs some time to examine what is possible.
