A separate DOM for each account

At this time, I can no longer have different browsers up to trade different accounts simultaneously. I like to trade different strategies with different accounts. When I open more than 1 DOM, ALL of them are linked to the SAME account even if I UNLINK the DOMs.

So, in order for me to trade multiple accounts, I have to keep changing the account in the dropdown every time. I am a scalper and constantly move the bid/offers. The current limitation of only trading 1 account at any given time is extremely constraining.
