Hi @<1523704207914307584:profile|ObedientToad56>

hat would be the right way to extend this with let's say a custom engine that is currently not supported ?

as you said 'custom' 🙂
None
This is actually a custom engine, (see (3) in the readme, and the preprocessing.py implementing it) I think we should actually add a specific example to custom so this is more visible. Any thoughts on what would be an easy one?
