Hi.

I would like to achieve a functionality in the Data Grid as shown in the image below. 

I need to create the following actions:

1.Only the rows uploaded in the Excel file will be selected.

2.The rows uploaded in the Excel file will be reflected in the Data Grid but not saved in the entity. They will be saved to the entity only when you press this save button.

It would be great if I could display data in the Grid that is not saved in the entity or force the checkboxes to be selected based on certain conditions, but it seems challenging.

Please provide guidance or examples using Data Grid API, JavaScript, or any other methods.

Regards,
