How do I combine the content from to capx files?

I have two different capx files, and would like to import the layouts and sprites from one of the projects, but are unable to find any methods to import them. Any advices, or do I need to dive into the code of the project files?

I generally drag and drop the images first, then copy and paste the whole events into the new .capx. Doesn't usually take too long, but a better method of importing (modular design is on the todo list) would be nice.

Yeah, did the same myself. But it would be great with a better way to combine two projects, so it would be easier to for example cooperate with different levels of the game.
