Angular - How to do inline batch update of checkbox columns in a modal / dialog window

I have a modal / dialog of an Angular material table with a couple of checkbox columns and other data from an api. How do I go about making inline updates on the checkbox columns and saving all the changes when I close the dialog and post to the api? I've looked at inline edit examples where you have to click edit on individual rows then edit and save each rows at a time. Requirement is to be able to just click on any checkbox in the table and save all changes.
