Dokan plugin Product Form changes

We intend to modify the forms that allows the vendors to introduce their products to the marketplace. In Dokan the users see the first page “Add-new Product” in which after the submission of this form they are send to the “Edit Product” page in which they can modify any mistake made. Add new Product page: [login to view URL] The two changes  Save Genre Data After input; We want to introduce a genre choice that is a taxonomy in the eyes of woocommerce, there was already a similar situation for category selection that we copy and paste changing the taxonomy name. Although we managed to display the choices, after you submit the form, it does not save the choices.  Insert Upload product option on the “add new product page” By default the Dokan plugin already gives the option to add a digital product (uploading the music), the problem is that this option only appears in the “Edit-Product” Page, that is after the vendor did the product first submission in the “Add-New Product” page. Therefore, we want to add this option in the “Add-New Product” page.
