You don't need to create 'dummy' 1099-DIV forms for your foreign dividends that are reported on a 1099-DIV from your US broker.
When entering your 1099-DIV, check the box to indicate 'I have more info..' and enter the amount of Foreign Tax reported on your 1099-DIV in Box 7 (screenshot).
This info will transfer for you to the Foreign Tax Credit section.

In the Foreign Tax Credit section, you enter the total amount of your Foreign Dividends and use one country 'RIC' to report this amount (screenshot).
