Make custom entity Look and feel similar to Holiday List

Hi All,

I am looking to creae two custom entities and have a parent child relationship between them. This is doable, but furthermore, I need to have the look and feel similar to Holiday Set available under Admin -> System -> Timings.

So, user goes and create a parent record (Holiday Set), and then creates child records (Holiday Names), all while staying on the same screen. Basically, something that we can call as Quick Entry or grid editor.

Is this possible?

Thanks,

Dhiraj
