Auto-import schemas into index file

[MichaelPrecel]

Is your feature request related to a problem? Please describe.
When working with a Sanity Studio, it's very rare that I will have a schema file in the schemas folder that I'm not importing into the studio. When developing rapidly, it's a frustrating step to have to always go in to this file and manually and explicitly import each file to place into the export array.

Describe the solution you'd like
Is it possible to automate this process? Possibly an option somewhere to turn on/off auto-imports.
