How to use Operator.arrayAppend on a relationship

Hi, is it possible to use any operator on a relationship column? I have a One to Many relationship column on a table and I would like to add entries to the column using the arrayAppend Operator. I'm hosting Appwrite 1.9.0 and using Flutter/Dart SDK. The following snippet:

await databases.updateRow(
        databaseId: AppwriteConstants.databaseID,
        tableId: AppwriteConstants.tableID,
        rowId: id,
        data: {
          "related": Operator.arrayAppend([id])
        }
      );

Fails with the error relationship_value_invalid Thank you!

As per what I've concluded from my search, relationship columns currently don't support operators. And in order to make any new updates, you should follow these steps:

1. Fetch the current row
2. Get existing relationship IDs
3. Append the new ID manually
4. Update the entire relationship field again

Yeah that's the workflow I am following right now. I was wondering if operators support was planned on relationship columns
