Can the column identifier is a foreign key to a model (ex: BoardColumn)?

[codebaradev]

In the documentation the Column identifie is a string, I want to change to a foreign key for my BoardColumn model. Is this possible? and how to call the column in Board if I use foreign key.

below is the example of database migration for a task using only string value for colummn identifier

Schema::create('tasks', function (Blueprint $table) {
$table->id();
$table->string('title'); // Card title
$table->string('status'); // Column identifier
$table->flowforgePositionColumn(); // Drag-and-drop ordering
$table->timestamps();
});
