Interactive Grid : How to update all selected items with the common value

Hi Team,

I'm working on requirement where I've to show the items in interactive grid and it has few columns like expiration date, capacity and groups etc.

In interactive grid I can search with any column and select the individual rows and update the values on each row.

My requirement is to select the items (bulk select) and update the group columns for all the selected rows with the same value.

I tried using the separate page items for group, date and capacity and written the logic in the save action process to update the row with the page item's value.
