Managing lessons split

Hello. I wonder whether there is a way to control the lesson split on import in any way? When I import my lessons I get something like 20 min chapter split into 17 min and 3 min. At the same time I see here in the library some books have full 30-50 min chapters without any issues. What is the way to get a full chapter?

No, that’s not possible at the moment. Splitting is handled automatically on each 2000 words.
