Websocket 账户信息推送能否推送子账户信息?

有没有能统一获取通过broker api POST /sapi/v1/broker/subAccount 创建的多个子账户的信息推送的功能?

比如主账户的listenKey,可以收到所有子账户的成交推送

No. The main account’s listen key will only provide access to the user data stream of the main account, not it’s sub-accounts.

To listen to all sub-accounts of a main account you are required to subscribe with the listen key of each sub-account.
