Datagrid 2 - select all checkbox

Hey, 

When using the DataGrid 2 widget and setting it up as shown in the below picture:

The user has the ability to use the check all toggle button but this only applies to all the objects that are currently rendered in on the page. This means that if the DataGrid has multiple pages, this check does not apply to any of the other pages than the one that is currently shown on screen.

Would it be a good idea to add a 4th option to have a  'select all the rows / objects' feature that can select everything over the multiple pages?

I'd love to hear your thoughts.
