How to update Form Extractor's Template Configuration

I’ve configured Intelligent OCR to read some documents using Form Extractor. Once I create a Template I could not find a way to open the Template Configuration screen, I can only Edit the Template but not the configuration, where I need to tune the OCR parameters such as timeout, scale, profile, … etc

Any hints are highly appreciated.

The only alternative for now is to recreate the Template from scratch again, which is time consuming in case of complex forms.

Appreciate any hints
Thanks in advance.
