Hello, I'm currently working on statamic v3 with the flat file storage driver on an existing Laravel app. My Laravel app has an other Back Office where I can create some records through the Eloquent ORM (Records are stored in the Database). I would add a select field on a Statamic Blueprint where I can choose between these Eloquent based records. I saw that an Eloquent driver already exists for entries, but I don't want my Eloquent Model become Collection/Entries in Statamic, and I want to stay with flat files in statamic. Have someone already experienced this usecase ? Is there a way to create a custom Field Type to make this working ? Thanks
