Can you clarify wether you want to remove the full block ? what does b/t

It does not work and I don't think it will be implemented. There was a bug
open for it, is was closed as WONTFIX.
Regarding path, please submit a detailed bug of whenever it works or not.

You can insert it in a Loop Controller it works.
This makes it really hard to have multiple CSV Datasets b/c they each
