Flatten All Positions and Cancel All Orders Across Multiple Accounts

There needs to be a feature where you can flatten all trades and cancel all orders across all of your accounts. Currently, you can only do this on each individual account. I have multiple that I trade together and when having technical difficulties and trying to exit quickly, it would be way easier to cancel all at the same time.

Yes need this. I thought the Exit All Positions Cancel All Orders did this across all accounts. Little did I know that when I woke up this morning I had an active order across 16 accounts that activated last night. I quickly scrambled and clicked each account to exit them.
