Possibility to add single or multiple content for schemes through cli

I was wondering if it is already possible to use the CLI and create schemes that have single content. Right now it is possible to import schemes with the cli but these are always ‘multiple content’.
Is this already possible? Otherwise, could this be added?

Using the sync command?

Yes for the .\sq.exe sync in command for instance, or .\sq.exe schemas sync

If you use VSCode you should get intellisense for the json files.

I think it should work to add a “isSingleton” flag to the properties, might it could be a bug that it does not work.

I tested it and it works as expected.
