Forms - Populate lines in related tables

[pajachiet]

Hi,

I like the fact that Grist forms are directly integrated with the underlying data structure, especially that Reference field values can be populated with data from the referenced table.

I would love that one could populate lines in related tables.

For example, I have a grist document to manage projects.
When I add a new Project with a form on the Projects table, I would like to have the option to fill multiples lines of the related Roles and Deliverable tables.

This would need nested forms, with multiple possible entries for the same entry in the table from the "main" form.

When only a few columns are filled with the nested form, a specific building block could be created, similar to "Columns" , but with a table.
