Containerapp revision with sidecar

[Jost3in]

Related command
az containerapp update

Is your feature request related to a problem? Please describe.
I would like to know if it is possible to create revisions with multiple/sidecar containers using cli? I have been looking for a soution but can not find any examples.

Describe the solution you'd like
Possibility to create revision with multiple images through cli

Describe alternatives you've considered
az containerapp compose - but this seem to create a new container app, not used to create revisions for existing app

Additional context
I have been considering using templates as well but also seem to create a new app. It is possible to create revisions with sidecars in the portal so I don not see why it should not be possible through cli
