Foreign Tax Credits for More Than 3 Countries

I received a T5 which summarizes foreign investments from 8 countries including Canada and the USA. They converted all the currencies to $USD (the investing account currency) and then to $CAD to report the interest income, dividend income and taxes paid. Some of the tax is withholding and some is non-resident tax. They provided a breakdown of these by security and country. From what I can find, the Turbo Tax Foreign Tax Credits form only allows 3 entries (I have the same issue with the T-1135 limit of 3 entries - still not fixed after 3 years of requests). Is there a way around the 3-country limit to claim foreign tax credits in Turbo Tax?
