Not easy, and at this moment not really supported( I think)
I managed to get it working sometime, but twice had an issue, as 1 course was from older version and I forgot that some parts were not correct. in the end had to remove the block and component, and do it all over.
What did I do? Same browser open AT in 2 tabs, 1 tab for new course, second with source info.
In the New course, click copy in the Block/Article you want the info (best to use a Blank at half), then go to the Source and Copy your info.
Back to new Course and Past at desired location.
If you need a lot more modules, it is easier just to copy the whole course.
