How to link Poloniex US account

I used to have a Poloniex account and I am based in the US. Poloniex split out from a company called Circle, so now to access my old Poloniex US account I have to log into a separate website at https://poloniexus.circle.com/. Am I able to connect this Poloniex Circle account to Cointracker for tax purposes? I only see the ability to link accounts from the main Poloniex website (poloniex.com).
