batch process 300 pictures with same filter !

Hi,
Glamour-douce looks very good for a lot of Sony A7s portraits I did at night at a wedding !
Would be simple I guess to add a batch mode when the chosen filter is the same for all pictures ! Indeed they already appear all processed in the navigation page ...
Just (!) add : Select all, de-Select all, Select (with usual Shift and CTRL) and ... a "Do It" button :)
