Directus. Display Create view for two models at once. Autobind to a directus user

I'm absolutely new to Directus. Please advice what to read to implement this. I have two models: Application and ApplicationMark.

Application:

• name

ApplicationMark

• a value of [1,2,3,4,5] // a mark of application
• application // an application that is marked
• user // a Directus user who marked the application

I want to display Application along with its ApplicationMark for the Directus user who marked it. How can I do that? What should I create? Custom layout? Custom view? Just guide me.

I've been able to do this via GUI. Directus is amazing! In my case I needed to create a relational field one-to-many on Application to ApplicationMark and users can edit both on Application model view.
