Hey Djamal S.,
I had the same issue and that's how I solve it:
- 1.
Filter the view, so it shows only the rows I want to check the checkboxes
- 2.
Check the checkbox in the first row
- 3.
Copy that cell (checked Checkbox)
- 4.
Scroll all the way down, hold SHIFT and clicl on the last cell
- 5.
Now all cells should be selected and you can simply paste the checked checkbox
