how to make 2-depth parameter relationship

i'm trying to create a custom shortcuts app action.

https://developer.apple.com/documentation/sirikit/adding_user_interactivity_with_siri_shortcuts_and_the_shortcuts_app

in section "Establish Relationships Between Parameters"

I want to make the 2-depth relationship (show if parent) between parameters.

but, I think the xcode ide supports only 1-depth relationship.

how to make belows?

example) Do not disturb ${enable} until ${until} ${time}

:CUSTOM_TYPE

enum 'enable' - [on | off]

enum 'until' - [turned off | time]

:RELATION

relation 'show if parent has exact value'

until -> enable:on

time -> until:time

Do not distrub {off}

Do not distrub {on} until {turned off}

Do not distrub {on} until {time} {2022/06/01}
