Best way to manage and preload multiple large scenes?

Because of the load? I’ve put in 4 of the 20 ‘conclusion’ scenes and already it is running sooooo slow. Is there a good resource on how to combine scenes from multiple files / documents?

edit: Ah, Ive found this: Linking to a specific scene from inside and outside of a Tumult Hype document I’ll give it a try.

another edit: okay I get how they switch scenes, but how do I combine two exports of Hype within one single HTML without them messing each other up.
