I would love to know the logic why the prebuilt lessons are not available when creating a custom lesson from the block option? As it is now, I'm mostly never using any of the prebuilt lessons as my content fits in custom lessons. I would love to be able to add, for example, a timeline within a block, or, a labelled graphic.
I'm not seeing the logic why they are not available in custom lessons?
Would it be possible to make them available in a future update?
