Is your feature request related to a problem?

I have step by step tutorial, where the next step in many cases rely on the previous step (lesson)
I find my self creating templates that are copies of the solution of the previous step - and though that this could be simplified.

I'm using the .tk-config.json to only put changed files in that template - but still that template is a copy of the solution of the previous step

Describe the solution you'd like.

I wish I could refer to a lesson in the template: option of a lesson

Describe alternatives you've considered.

Create a lot of templates - less fun
