vGiP2L8A the ASIAIR doesn't support a dual scope setup. It never has. It's always been more focused on simplicity which comes with limitations.
For more complex setups such as dual scope setups etc you're much better off going with a mini-pc such as a Quieter 3/4C running Windows with tools such as NINA.
In general, never buy a product based on future, unreleased, functions or functions you hope will be supported. Always buy or use a product based on what it does now.
