Edit bulk rows through looker action hub (How to provide user comments for multiple rows in looker data)

[LazyLearner]

I have a scenario, like in my dashboard i have a table view kind of look, where i have provided a data action… i want user to provide input comments, and then i want to store those comments in the database and show back to the looker dashboard.

These user input comments will be shown for each row in the looker. This one i am trying through looker data action where i need to build a cloud function to capture the comments and write back to database.

But i have a urgent required like instead of getting a single row inputs from the user, i want to get same user input comments for bulk/multiple rows in the table.

Can anyone please guide me how to complete this task?
