I have downloaded them and because they were at a 3rd party cloud it wouldn't let me add them to itch.io app. Is there a way to add if I place them all in the same directory? If not could you add that feature? 

I am not an expert in the Itch application, but I remember reading some similar posts and I think that currently there is no way to import games.

If you downloaded them from your browser, than you can’t import them. If you had an game installation directory from a previous app install, then you should be able to add that folder as a game install location and it will be able to pull in the installed games.
