Field Component-Sub Table-Possible to make Auto Increment selected record

Hello,

As view on below image, any how to make a “Add New” record duplicate or auto increment? Example like “Time Start” first line date is 01/10/2024, and when click “Add New” this second line record auto increment and fill as 02/10/2024… This is example. Maybe Linkage Rules able do more for the function/control for related data.

Thanks.

Requires development to achieve.
