Grid2 Deselect rows in microflow after processing

I have a Grid2 list with Multi selection in checkboxes and the Show check all toggle enabled. The user can select multiple rows and hit an action button in the header to process the selected rows. These processed rows stay in the list (no delete or changed status). After the processing all the checkboxes are still selected. The user can ofcourse hit the toggle button (twice) to deselect but I would like to deselect  all succesfully processed rows (set each checkbox to false). Any idea how I can get this done?
