Change standard product to virtual in products mass changer

I have the need to change some products from my Prestashop store from standard to virtual, but without adding any downloadable file. I sell online courses and the registration is made by a script that executes after the purchase. So it would be great if you include the field is_virtual from the table ps_products in the products mass changer. It has only two values, zero for standard products and one for the virtual ones.

Thanks and best regards
