Hello,
I use custom data sources for aliyun.
I expected use a custom variable format options ,
The format options cannot support my query.

I found the code, about variables format.

github.com

grafana/grafana/blob/main/public/app/features/scenes/variables/interpolation/formatRegistry.ts

import { isArray, map, replace } from 'lodash';

import { dateTime, Registry, RegistryItem, textUtil } from '@grafana/data';
import kbn from 'app/core/utils/kbn';
import { ALL_VARIABLE_VALUE } from 'app/features/variables/constants';

import { VariableValue, VariableValueSingle } from '../types';

export interface FormatRegistryItem extends RegistryItem {
  formatter(value: VariableValue, args: string[], variable: FormatVariable): string;
}

/**
 * Slimmed down version of the SceneVariable interface so that it only contains what the formatters actually use.
 * This is useful as we have some implementations of this interface that does not need to be full scene objects.
 * For example ScopedVarsVariable and LegacyVariableWrapper.
 */
export interface FormatVariable {
  state: {
    name: string;
