How to export all subgrid record data to Word Template

Hi All,

I have created a word template for an entity and uploaded it. On the entity form, there is a subgrid related to another entity. So while creating the template I have also imported the relation. But when I enter multiple data in subgrid and try to export the template only the last data entered in the subgrid is shown.

The question is how to import all subgrid data(not only last entry) to word template?
