Integrating account software with 2 different base currencies?

Hi all, we're a small company with a Canadian and US presence, hence we have 2 different ledgers in CAD and US.

Currently we just have 2 Sage50 Companies set up, one for Canada and one for US while using ZohoCRM. We're interested to integrate Accounting and CRM together and there is Zoho Books as part of the Zoho One Suite but it doesn't allow 1 CRM -> Multiple Organizations of different base currencies (CAD$, US$).

What options are out there for organizations like ours?
