Conditional logic based on Shopify (default) options

Shopify Apps
1

Hi

The default options I have created in Shopify are

  1. Colour (1)

  2. Colour (2)

  3. Size

I want to create conditional logic to show additional options based on the above three Shopify selections. The problem I have is that all Option apps I have tried downloading only allow me to set conditional logic based on the options created within the app. They do not allow me to set conditional logic on the default options (as shown above)

Any suggestions please?
