Hi, I need to add a new

@isUnique

field to an existing type in my schema. When adding a new field, it requires a

@migrationValue(value: "something")

. But since the field is supposed to be unique, I can't give a static migration value. Is there a way to give randomly generated values within the

types.graphql

document, or to reference another existing field in some way to fill this newly generated field?
