How to Groupe Customer field in the Wrike template

Hi, 

For one of my project, I would like to use Wrike task as Check list. For my need, I am creating many (>15) custom fields which have to be filled up by the operator. 

From Custom Item Type, I know it is possible to change the order of the custom files (https://help.wrike.com/hc/en-us/articles/4409188763031-Custom-Item-Types-in-Wrike).

It is a good start, but to increase the readability, I would like to create "section", regrouping multiple custom fields (one section related to people, the other one to costs, etc). 

Do you know if it is possible to do it ?
