if I prepared my Machine Learning features separatly and I wanna combine them now for modelling, is it a good practice or might be needed that I should configure the selected features from a yaml config so i can control turning on and off the features ?

depends what you want to do, and how dynamic -- what's the workflow that you're trying to create? Can you explain that a bit more?

I think I have my question answered, thanks a lot stefan for your support, really appreciate it
