How to link account to another cTrader ID?

I have two accounts with two different brokers under one cTrader ID.

Is there a way to link one of the accounts to another cTrader ID so I can use cTrader COPY for my own internal use (as a copier)? 

As I checked I cannot copy my own strategy from one account to another under the same cTrader ID and I don't want to use third-party copier.

Thanks!
