Hello Leon,
I'm not sure if it would be so easily achievable as it is in QlikView.
Here is an idea. Encode data in QlikView and extract data model tables into qvd files by putting a store statement at the beginning of the script and doing the Partial Reload. Make sure you will put exit script just after all store statement lines.
Import qvds into QlikSense and there you go! 
Cheers!
