How would I do interactive dialog in Unreal 4?

Can Unreal 4 handle thousands of lines of Interactive text Dialog with cutscenes and audio for a storyline driven game?, and if it can how would you set this up in Unreal 4? Unreal 3 UDK had a pop-up Text Announcement System but I don’t see this in Unreal 4, I don’t see a text and audio dialog editor for Unreal 4 for doing interactive storyline driven RPG games.

You can use Widgets to display any type of graphic, text, or buttons you want. You’ll probably want to store your conversations in custom tables, and your responses in a savable class attached to your player.

If you want to use a solution that already exists, there are some on the marketplace.
