Mark all - custom column action in Enterprise

Do you know how to add a custom column action (like “Delete all”)?

I need to add a custom action, something like “Mark as Draft” or at least to have something like “Select all” and a separate button outside the grid that I can do whatever with the selected items…

Hello
It is not the CRUD you are using.

But you could go back in time a bit and see how this functionality is implemented.

It is implemented in CI3
